feat: restore last conversation on launch (optional setting)

[gaursomya777-dev]

What problem does it solve?

When AionUi launches, users always land on the welcome/GUID screen even if they were deep in an active conversation yesterday. Power users who keep long-running agent sessions open lose context and have to hunt the sidebar every cold start.

Proposed solution

Add a System setting: On launch → Open last conversation (default off, preserves current welcome behavior).

Behavior:

1. Persist lastConversationId when the active conversation changes (or on app quit).
2. On desktop ready / first route resolve: if setting is on and the conversation still exists, navigate to it; otherwise fall back to GUID.
3. If the conversation was deleted or fails to load, clear the stored id and open GUID (no error wall).
4. Optional later: "always GUID" / "last conversation" radio — start with a single toggle.

Scope

Desktop renderer routing + a small config key (system.openLastConversation or similar). No aioncore changes.

Willing to implement it yourself?

Yes — please convert to a bonus issue assigned to me for the AionUi × Kimi campaign if accepted.

Implementation ready

Hi @IceyLiu — full implementation is ready for this proposal:

• PR: feat(system): restore last conversation on launch (optional setting) #3744
• Branch: feat/restore-last-conversation-on-launch
• Setting default off; pure helper + unit tests; System UI + i18n (13 locales)
• Restores only once per session from GUID; falls back if conversation was deleted

Please convert this proposal to a bonus issue assigned to gaursomya777-dev so it can count for the AionUi × Kimi campaign. Happy to link the issue number on the PR once assigned. Thanks!

Status after #3726 merge

Hi @IceyLiu — thank you for merging #3726 today.

Still need one more assigned bonus track for the Kimi campaign (currently 1/3 valid merges; #3717 is the other open assigned track).

This proposal already has a full green PR:

• PR: feat(system): restore last conversation on launch (optional setting) #3744
• Optional setting (default off), pure helper + unit tests, System UI + 13-locale i18n
• Restores last conversation once per session from GUID; safe fallback if deleted

Please convert this discussion → bonus issue and assign gaursomya777-dev so #3744 can count. Happy to retitle/link the issue number immediately after assign. Thanks!

Status update — 2/3 after #3717

Hi @IceyLiu — quick follow-up with new info since Jul 27:

• fix(tray): honor close-to-tray on custom title-bar close (#3669) #3717 (close-to-tray / fix(tray): close button does not minimize to tray on Linux when closeToTray is enabled #3669) is now merged — thank you. Campaign score is 2 / 3.
• This proposal still has a full green PR ready:
  • PR: feat(system): restore last conversation on launch (optional setting) #3744
  • Optional setting (default off), helper + unit tests, System UI + 13-locale i18n
  • Restores last conversation once per session from GUID; safe fallback if deleted

Please convert this discussion → bonus issue and assign gaursomya777-dev so #3744 can count as the 3rd track. Happy to retitle/link the issue number immediately after assign.

If you prefer a different track instead, any of these also work (all green):

• Discussion feat(system): Start minimized to tray (optional setting) #3735 → PR feat(system): Start minimized to tray (optional setting) #3741 (start minimized)
• Issue [Bug]: Provider 设置中缺少 is_full_url 开关，非标准 API 路径的模型无法自助配置 #3514 → PR feat(settings): expose is_full_url toggle in Edit Provider modal (#3514) #3720 (is_full_url toggle)

Thanks!
