0.4.4 — Tab Bar Enhancements, Installer Update & Integrity

Released — current version

Tab Bar Enhancements

• Tab bar position — top, left, bottom, or right

• Maximum simultaneous open tabs — enforced when opening new tabs

• Close confirmation — warn when closing a tab with unsaved state (requires has_unsaved() hook)

• Multiple tabs of the same screen — verify _unique_display_name() behaviour holds correctly with split layouts from 0.4.3

Update-in-Place Installer

• Installer detects an existing installation at the target path by reading .VIS/install_log.json

• Compares archive checksums against installed files and only extracts changed or new files

• Preserves user-modified files (e.g. settings) unless explicitly overwritten

• Reduces install time for updates compared to a full reinstall

Rollback on Failure

• If extraction fails mid-install, the installer cleans up all partially extracted files

• If updating an existing installation, previous state is restored from a temporary backup created before extraction began

Verify Installation

• Post-install integrity check confirms all expected files are present and match expected sizes from the archive

• Triggered manually from the installer menubar or via --Verify in quiet mode

Installer Menubar

• Installer GUI gains a menubar with an “Options” dropdown

• Entries: “Run Uninstaller” (launches uninstaller if installed), “Verify File Integrity” (runs check against install_log.json)
