Every existing plugin slot renders wherever it's placed in the page (a
toolbar row, an attachment's hover-action bar, etc.) and is constrained
by that spot's own CSS - fine for small controls, but there's no way
for a plugin to show a large custom UI (a graphical file browser, a
multi-step wizard) since even a position:fixed overlay rendered from
inside such a slot is clipped to the surrounding row's own layout, not
the real page (confirmed live building the webdav-storage plugin: a
folder browser rendered but was squeezed into an unusable sliver).
Adds:
- host-dialog.ts: new 'custom' DialogKind + awaitCustomDialog(), reusing
the existing confirm/alert/prompt queue plumbing.
- host-api.ts: 'ui.openDialog' API method.
- runtime.tsx: sandbox-side api.ui.openDialog(opts) proxy.
- plugin-types.ts: new 'plugin-dialog' SlotName - a plugin implements
this slot with its actual custom UI.
- plugin-dialog-host.tsx: renders the requested slot via the existing
PluginIframeSlot INSIDE the dialog's real app-root fixed overlay
(position: fixed; inset: 0, above everything) instead of the
confirm/prompt form, for kind: 'custom'. Resolves via a generic
onResult callback in extraProps (marshalled the same way
composer-attachment-source's onAttach already is - no new plumbing
needed there).
A plugin calls api.ui.openDialog({ slot: 'plugin-dialog', extraProps,
title, width }) and awaits the Promise, which resolves to whatever its
own slot component passes to props.onResult(), or null if the user
closes the dialog without doing so.
Two new extension points for third-party attachment/cloud-storage plugins
(e.g. a WebDAV/Nextcloud file browser), neither of which the plugin API
currently supports:
- attachment-actions: a new slot rendered into every attachment's hover
action row (all six render paths: beside-sender/below-header/mobile,
each in its compact and expanded-popup form), with the AttachmentInfo
(name, type, size, blobId, emailId) passed through extraProps. Lets a
plugin offer a 'save this attachment elsewhere' action next to the
existing download/preview buttons - previously the only per-attachment
hook was the read-only onAttachmentDownload observer.
- composer-attachment-source: a new slot rendered in the composer toolbar
next to the existing composer-toolbar slot, with an onAttach(upload)
callback in extraProps. Lets a plugin that has already uploaded a file to
the JMAP server itself (api.jmap.uploadBlob) - e.g. a file picked from an
external cloud storage browser - have it added to the current draft as a
real attachment. Previously there was no way for a plugin to add an
attachment to the draft at all; the closest existing mechanism
(onBeforeBlobUpload's ExternalAttachmentResult) only replaces a locally
picked file with body text/a link, it cannot add a brand-new attachment
from an external source.
Both slots follow the existing PluginSlot pattern (calendar-event-actions):
render nothing when no plugin offers the slot, so this is purely additive.
Motivating use case: the existing nextcloud-attachments community plugin
uploads local files to Nextcloud and appends a share link to the message
body - useful for large files, but there was no way for a plugin to do the
inverse (attach a file that already lives in cloud storage as a real binary
attachment, not a link) or to let attachment recipients save an incoming
attachment back out to their own cloud storage. These two slots make both
directions possible without touching plugin-store or the sandbox bridge -
existing slot/extraProps plumbing (see calendar-event-actions) already
supports arbitrary POJO props.
After a reload the unified mailbox showed only the active account's mail;
other accounts appeared only once visited. Intermittent (~1 in 14), and
not a timeout - nothing on this path uses setTimeout/AbortSignal/race.
checkAuth awaits only the active account and restores the rest in a
fire-and-forget background loop, registering each client only after
connect() resolves. buildUnifiedAccountClients drops accounts with no
live client (`if (!c) continue`). And isConnected was persisted, so it
rehydrated stale-true: the account passed the isConnected filter while
failing the client lookup, and connectedAccountsSignature already looked
complete at mount so nothing re-fired - and the effects keyed on it only
recompute counts, never the list.
Clear isConnected/hasError on rehydrate so both the filter and the
signature describe this session, and refetch the open unified/cross list
when an account joins the connected set (growth only, not on first
render, not while a search owns the list). Extracted
connectedAccountsGrew so the membership check is testable without
rendering MailApp.
Verified the reset cannot block reconnection: checkAuth reads the full
account list and never filters on isConnected.
Fixes#950
Switching folders currently keeps an active search applied and re-runs
it in the newly selected folder — deliberate behavior from #553, where
users wanted the query to follow them across folders. Others expect the
opposite: clicking Inbox/Sent should drop the search and just browse the
folder.
Add an opt-in setting (Settings → email behavior) that reconciles both.
Default is off, so #553's search-follows-you behavior is unchanged for
everyone. When on, any folder click clears the text query and advanced
filters and browses the folder instead of re-running the search.
Applied uniformly across the four folder-entry paths in MailApp — normal
mailboxes, per-account (Pro sidebar) folders, unified views, and cross
views — via one helper so no path diverges.
Opening the toolbar feeds its height back into scrollTop so rows keep
their position on screen. At the top of the list there are no rows above
to hold steady, so that scroll instead slides the first message under the
toolbar — select the top message and it disappears behind the bar acting
on it.
Skip the compensation when the list is already at the top and let the
content move down there, which is what the toolbar taking up space
should do. Mid-list behaviour is unchanged, and the scroll is clamped at
zero so collapsing the toolbar cannot drive it negative.
