Features

Split Pane / Dual Pane Layout

Two independent panels sit side by side, each with its own folder tree and bookmark list. Browse one panel while the other holds your destination — no need to navigate back and forth.

All panel and tree widths are fully adjustable — drag the splitter between the two panes to resize them, and drag the divider between the folder tree and bookmark list within each pane to tune your layout.

Folder Tree Navigation

Filter folders to quickly find and open any folder
Collapsible folder tree with depth-indented hierarchy
Each folder displays a count badge showing the total number of bookmarks it contains, including all subfolders recursively (URLs only)
Back / Forward / Up to Parent navigation buttons

Bookmark List

Sortable columns: Name, Path, URL, Date Added
Sorting is for browsing only — it does not affect the original order in the browser
Resizable columns and panels via drag handles — all fully collapsible
Virtual scrolling for smooth performance with large bookmark collections

Searching

Search bar with live filtering and highlighted matches. Path column appears automatically in search mode, allowing users to sort bookmarks by containing folders.

Move & Organize

Move selected items to the opposite panel via drag and drop, toolbar, context menu or popup buttons
Move popup buttons appearing on the panel divider for quick one-click transfer — two independent arrow buttons, each enabled only when its source panel has a selection. The buttons can be freely repositioned by dragging.
Cross-panel selection is preserved when switching panels — selections in both panes can coexist.
Cut / Paste support (Ctrl+X / Ctrl+V)
Undo / Redo (Ctrl+Z / Ctrl+Y)
