v5.1.4fixMay 28, 2026

· What's New modal no longer competes with the Create Table prompt — they now appear sequentially instead of simultaneously.
· Toast notifications now appear above all modals.

v5.1.3newMay 28, 2026

· Report / Feedback button — send bug reports or feature requests directly to the developer from the top bar.

v5.1.2fixMay 28, 2026

· On first visit, the What's New modal now correctly appears in front of the Create Table prompt instead of being hidden behind it.

v5.1.1fixMay 12, 2026

· Mouse wheel zoom and pan are now properly dampened — no more jarring jumps when scrolling with a mouse instead of a trackpad.

v5.1.0newMay 12, 2026

· Keyboard shortcuts in dialogs — press Enter to confirm and Escape to close, now working across all modals.
· Clicking outside a dialog now reliably closes it — previously Export, Share, and delete confirmations would stay open.
· When clipboard access is blocked, the share link is placed in the address bar so you can still copy it manually.
· Notification banners now wrap their text to fit the screen instead of overflowing off the edge.
