Mobile: hide projects you don't work in, remember the project sort, and sort threads by latest activity

[AdEx-Partners-DE]

Problem

On the iOS Nightly app I connect to one server with 47 projects. In the last seven days I typed in 16 of them, and most days in only a few. Getting to those takes scrolling every time:

1. Every project is always listed. Mobile has no way to hide or archive a project from the home list. I keep old projects on the server on purpose and don't want to delete them just to shorten a list.
2. The project order resets. The sort choice in the filter menu (updated_at or created_at) lives in React state (HomeListOptionsProvider in apps/mobile/src/features/home/home-list-options.ts). After the app restarts it is back to the default, and there is no order by name.
3. Threads don't sort by latest activity. The active thread list follows its arrangement order (activeOrderKey: creation, last un-settle or a manual drag). Mobile never reads the existing sidebarThreadSortOrder setting, so the threads I just worked in don't come to the top. Mobile home: surface new agent replies (sort by latest reply, unread marker, reply preview) #14196 describes the same thing from the agent-reply side.

Proposal

• Hide a project from the list, from its long-press menu and in Settings, with a "Hidden projects" list there to bring it back. Hidden projects keep their threads, and a thread that needs me (a question, a failure) still shows. This could live in the shared settings so desktop can follow later, but mobile alone would already help.
• Remember the project sort across launches, and add by name next to "recently updated" and "recently created".
• Let the thread list follow sidebarThreadSortOrder on mobile too ("recently updated" puts the threads with the newest activity first), as the desktop sidebar does.

Smallest useful scope

Persisting the project sort choice, since it's a client-only change to an existing control. Hiding projects is the part that saves the most scrolling.

Not proposed

No change to how projects are stored on the server, and no deleting.

Thanks for the detailed write-up. Two of the three parts are already tracked:

• Hiding projects is covered by Archive and unarchive whole projects #16166 (archive and unarchive whole projects), and open PR feat: pin favorite projects and archive old ones #15990 implements it, including mobile: archived projects leave the pickers and mobile lists without deleting anything, and mobile Settings gets Pin and Archive.
• Sorting threads by latest activity on mobile is Mobile home: surface new agent replies (sort by latest reply, unread marker, reply preview) #14196, as you noted.

The part that's new here is remembering the project sort across launches (today only the environment and project filters are saved to mobile preferences) and adding a by-name order. Let's keep this discussion focused on that, and follow the other two in their own threads.

Thanks, that split makes sense. I'll follow hiding projects in #16166 and #15990, and the thread order in #14196.

For the part that stays here, the first half is ready on a branch: the sort choice is saved together with the environment and project filters that HomeListOptionsProvider already persists. projectSortOrder becomes an optional field of ThreadListFilters, so preferences saved by older builds still load. Three files, +38/−7 (compare), including a test that restores a saved created_at order on launch and saves a new choice. Checked on Windows: home-list-options.test.ts and the preference tests pass (10 of 10), tsc --noEmit in apps/mobile is clean. Not checked: on a device.

By name is the larger half, because HomeProjectSortOrder comes from the shared SidebarProjectSortOrder (updated_at, created_at, manual). It could either become a new value there, so the desktop sidebar can offer it too, or stay a mobile-only option.

Would you take the persistence change as a small pull request now, and which way would you prefer for sorting by name?

A short update, since the mobile code moved under this request. #25813 (27 Oct) made the home list derive its options and save the environment/project scope in the mobile preferences. The sort order is the only part still reset on every launch; the code comment says so: "Only the scope persists; the sort order is per session."

That makes "remember the project sort across launches" much smaller than my earlier branch. I rebuilt it on current main: feat/mobile-remember-project-sort-v2 (6c00d1a01c).

• One optional projectSortOrder field in ThreadListFilters, so preferences that were already saved still decode.
• The sort order is saved through the same savePreferences call as the scope, and read back on start.
• 13 changed lines of production code.

Checked on Windows: both home-list-options.test.tsx cases fail on unmodified main and pass with the change. The first saves the sort with the scope, the second restores it from saved preferences. The apps/mobile typecheck exits 0 and lint on the three files exits 0. Not checked: a real device or simulator run.

"By name" stays out of this, as you suggested it is separate. If the per-session sort was deliberate, a one-word answer is enough and I'll drop it. Otherwise, should I open this as a PR?
