The tabs UI lacked per-file options (rename/duplicate/delete), auto-renamed files based on content, prevented deleting the last tab, and had no reset mechanism.
Changes
Per-file options menu
⋯button that opens a dropdown with Rename, Duplicate, and Delete actions — available on all tabs including the Welcome fileEnter/Escape); Duplicate inserts a(copy)tab immediately after the sourceDelete & last-tab behavior
tabs.length <= 1guard fromcloseTab()— any tab can now be deletedUntitled Ntab instead of blockingSequential, stable file naming
deriveTitleFromContent()and the debouncedupdateActiveTabTitle()— files no longer auto-rename from editor contentUntitled 1,Untitled 2, etc. via a monotonically increasing counter persisted inlocalStorage; numbers are never reused after deletion+Create button placementrenderTabBar()at the end of the scrollabletab-list, keeping it visually adjacent to the last tabReset
