Lataa mnml v0.2.20

Release Notes
A file manager, background file operations, and three separate editor
freezes fixed. The performance work matters most if you open large
files: mnml could lock up for minutes on a minified JSON file or on a
13,000-line source file, and both are now fast.
Added
- Files pane — a directory listing as a first-class pane
(files.open), so a file browser is just another thing you can split,
tab, and arrange. Navigation, sort, hidden-file toggle, a clickable
breadcrumb with a destinations picker (Home / Downloads / volumes /
workspaces / recents), git status badges per row, and p to preview
a file without leaving the listing.
- Multi-select in that pane. Space marks, a marks all, Esc
clears; every operation acts on the set. Reachable by mouse too —
Ctrl/Cmd-click toggles one, Shift-click extends a range, and the
right-click menu acts on the marked set rather than silently on the
row under the cursor.
- Dual file panes (commander layout) from the + menu.
- Background file transfers. Copy and move run off the render
thread, so a large directory can no longer freeze the editor. A
statusline chip shows progress and speed while one is running, hidden
entirely when nothing is; transfer.cancel_all in the palette.
- Notification history. Every message already recorded to
:messages now persists per workspace and survives a restart, with a
statusline badge counting unread warnings and errors. Info does not
light it.
- Submenus in context menus, and the + menu regrouped from ~15
flat rows into five. Each row carries a kebab for pinning, hiding, or
copying its command id, and your layout persists.
- TODO actions. The TODOs panel offers to hand a marker to an AI
session, listing whatever agents, commands, and skills the workspace's
own .claude/ directory contains, and falling back to plain Claude
Code or Codex when it has none.
- --no-session (also ./run.sh fresh) launches without restoring the
previous session — an escape hatch for the case where a restored pane
wedges the app and relaunching reopens it.
Fixed
- Three editor freezes on large files. A single very long line (a
minified 545 KB JSON file on one line) made the renderer redo
whole-line work for every visual row. Separately, line lookups scanned
the entire buffer on every call, and the statusline breadcrumb ran a
regex pass over the whole file every frame. On a 13,000-line file,
frame time went from 300 ms to 9 ms.
- Horizontal scrolling rendered nothing. With line wrap off, the
view window never moved, so anything past the viewport width on a long
line was unreachable and the cursor drifted off the character it was
on. Long-standing; found while reviewing the performance work.
- PageDown on a short file parked the cursor past the end and
painted a blank pane.
- Scroll acceleration is calibrated for terminals that multiply wheel
events, and defaults to a sane setting.
- Git panel: the rail scrolls, tags list newest first, a collapsed
section's count no longer changes as you scroll past it, and clicking
a branch reveals its commit with context instead of pinned to a screen
edge.
- The + dock chip no longer paints over the bottom-right pane's last
row, where clicking a file created a sticky note. Its actions moved
into the + menu.
- A menu left open no longer keeps the keyboard after a Ctrl+punctuation
chord.
Security
- Hardened the GitHub Actions workflows: event-supplied values reach
shell steps as environment variables rather than being interpolated
into the script, and every workflow declares least-privilege
permissions. Both classes were reported by code scanning.
