Sidebar

The sidebar (toggle with Mod+B) is organized as an activity bar with five panels:

Database explorer — browse databases, schemas, tables, and columns of the connected source. Its search box filters as you type; the history button on the right opens recent searches (up to 8) to pick from. Press Enter to commit a search. The toolbar locate button (or Reveal in sidebar on a table or file tab's context menu) expands the tree to that tab's node and scrolls it into view. SQL editor tabs are not locatable—the button stays disabled and the menu item is hidden.
Favorites — pinned tables and saved SQL for one-click access, searchable.
Code — local SQL workspace folders and files.
Query history — previously run queries, searchable.
Tabs — a vertical list of open editor tabs grouped by connection. Built for many-tab sessions, with built-in search to find a tab by name. Right-click a tab for the same context menu as the main tab bar (close, split, favorite, and more).

Position

The whole sidebar (activity bar + panel) can be docked on the left or the right:

Right-click the activity bar background and pick a side under Sidebar position.
Each panel can also be docked independently: right-click its activity bar button and choose Left, Right, or Follow sidebar.
Left and right panels can be open at the same time — one per side — each with its own resizable width.
Position and widths are persisted and restored on the next launch.

Right-click a connection in the database explorer to:

Rename (F2)
Properties (F3)
SQL editor (F4)
Refresh (F5)
Export connection
Move up / Move down — reorder connections in the list (disabled at the top or bottom). Order is persisted and restored on the next launch.
