[FEATURE]: Desktop Session Management Crisis — Restore Delete & Fork actions and unblock stalled PR #11684

Feature hasn't been suggested before.

• I have verified this feature I'm about to request hasn't been suggested before.

Describe the enhancement you want to request

Summary

The Desktop app (and to a lesser extent the TUI) is in a session management crisis: there is no way to delete a session from the UI, the fork action was deliberately removed over a year ago and never restored, and a working PR that adds a /delete command (#11684) has been sitting unreviewed for 6 months.

This is the single biggest UX gap for anyone who uses OpenCode Desktop daily. Sessions accumulate endlessly with no cleanup affordance, and the only workaround is the CLI (opencode session delete <id>).

Related Issues (all pointing to the same gap)

The problem has been reported multiple times in fragmented issues:

Issue	Description	Status
#40786	Home page session list has no delete/archive entry point	Open
#38820	Right-click to delete sessions on desktop	Open
#33129	Add delete button for sessions in sidebar	Open
#37277	Restore a direct archive action for sessions	Open

The Fork Button Was Removed and Never Restored

• The fork button was originally added in fbd9b7cf4 (PR #17092)
• It was removed in 311ba4179 with the message "fix(app): remove fork session button" as a workaround for a crash (#18250: "Platform context must be used within a context provider")
• It was never restored, despite the crash being platform-specific
• Issue #22205 requesting restoration was closed as "not planned"
• A new feature request for Desktop fork button (#25582) recently auto-closed due to inactivity

Stalled PR: /delete Command (#11684)

• PR #11684 by @frouo implements a /delete slash command with confirmation dialog
• It was opened February 1, 2026 — over 6 months ago
• It has zero reviews from maintainers
• Multiple users in the comments are asking for it to be merged
• Meanwhile, the community is resorting to writing external scripts and tools to delete sessions

Technical Evidence

From #40786 (analysis of the app bundle v1.18.14):

• HomeSessionRow has no onContextMenu handler — right-click does nothing
• The archive button is gated behind SHOW_HOME_SESSION_ARCHIVE = false — a hardcoded constant, so it's never rendered
• The delete dialog only exists inside an open session's timeline header menu, requiring users to open a session before they can delete it

Proposed Solutions

1. Merge PR #11684 — at minimum, unblock the /delete command for TUI users who prefer keyboard-driven workflows
2. Add a delete button to the Desktop Home page session list — either as a hover button, a right-click context menu, or a three-dot menu on each session row
3. Restore the fork button — the original crash (#18250) was a platform context issue that should be investigated properly rather than removing the feature entirely
4. Consolidate the fragmented requests — there are now 4+ open issues asking for the same thing; a coordinated response would help the community

Impact

As a daily Desktop user, my session list grows indefinitely with no way to clean it from the UI. The only option is to open a terminal and run opencode session delete <id> — which feels like a developer alpha tool, not a v1.18 product. For users who are less comfortable with CLI, sessions are effectively permanent.

This issue was filed after researching #40786, #38820, #33129, #37277, #22205, #25582, #11684, and the commit history. It consolidates multiple fragmented requests into one actionable report.
