Session plugin

Restores your working state between runs of the editor — open files, the active tab, each file's caret position and the split-view layout — so you can pick up exactly where you left off, including changes you hadn't saved.

Where to find it

The File menu:

Command	Shortcut	What it does
Open Recent ▸ …	—	The last N opened files, plus Clear.
Reopen Closed Tab	Ctrl+Shift+T	Reopens the most recently closed file.

What it restores on startup

• The set of open files and their tab order, with the previously active tab.
• Each file's caret position.
• The split-view layout — which document sits in which pane, and the panes' relative widths.
• Unsaved changes (when enabled) — buffers with edits you hadn't saved come back as they were.

Settings

Preferences ▸ Plugins ▸ Session:

Setting	Range / default	Effect
Restore previously open files on startup	on by default	Master switch for reopening last session's files.
Number of recent files	up to a fixed maximum	How many entries the Open Recent menu keeps.

Unsaved changes

A group that controls keeping edited-but-unsaved buffers across runs:

Setting	Range	Effect
Keep unsaved changes between runs	on/off	Master switch for the buffer-persistence feature below.
Save unsaved buffers every	2–120 s	How often unsaved buffers are snapshotted to disk.
Skip buffers larger than	64 KB – 256 MB	Buffers above this size are not snapshotted (keeps the feature cheap).
Discard orphaned snapshots after	1–365 days	How long a snapshot for a file you never reopened is kept before cleanup.
Include untitled buffers	on/off	Also persist never-saved "Untitled" buffers, not just edited files.

Closing safely

With Keep unsaved changes on, closing the whole window with unsaved edits is a supported flow — the content is snapshotted rather than prompting. Closing an individual tab still prompts, since that forfeits its snapshot. If the file on disk changed under a kept buffer, the plugin prompts to resolve the conflict on restore.
