CHANGELOG.md

@@ -6,10 +6,15 @@
 - TUI host list footer now includes `Ctrl+E:edit`
 - New hosts/keys/snippets created via TUI form now get UUID + timestamps (`CreatedAt`, `UpdatedAt`)
 - Storage layer auto-generates UUID + timestamps on save if empty (defense-in-depth)
+- **host_form_tab.go**: Space/Left/Right keys now passthrough to text input when not on auth type field (fixes typing spaces and cursor navigation)
+- **tui.go**: Key and snippet list tabs now properly refresh after save/delete (mirrors host flow)
+- **tabs.go**: WindowSizeMsg now forwarded to ALL tabs, not just the active one (fixes stale dimensions after resize)
 
 ### Changed
 - All tab footers are now context-specific (no global status bar)
 - SFTP browser uses full-width panes (`t.width/2`)
+- **sftp_browser_tab.go footer**: Added `Enter/→:open`, `←/Backspace:up`
+- **form tabs footer**: Added `Shift+Tab:prev`, `↑↓:nav`
