 ## Unreleased
 
 ### Added
+- Added independent `row_gap` settings for expanded Space and Agent sidebar entries. (#873)
 - Copy mode now supports literal smart-case search with `/` and `?`, repeating with `n` and `N`, match highlighting, and tmux-style cross-line `w`/`b`/`e` word motions. (#1230)
 - Added maki detection with idle, working, and blocked screen states. (#1301, thanks @tontinton)
 
+### Changed
+- Expanded Space and Agent sidebar entries now use a packed layout by default; set the corresponding `row_gap` to `1` to restore the previous spacing. (#873)
+
 ### Fixed
 - Outer-terminal focus gained and lost reports now reach the focused pane when its application enables focus reporting, restoring Neovim file autoreload and other focus-aware terminal behavior. (#1337)
 - Native Windows servers now detach from the terminal console that launched them, so closing WezTerm, Windows Terminal, or another host terminal no longer stops persistent pane processes. (#1329)

 Tokens render in their configured order. Herdr normally separates adjacent values with ` · ` and uses a single space after `state_icon`. Missing values and their separators disappear; a row disappears when none of its tokens have a value. Each layout may contain at most 16 rows, with at most 16 tokens in each row.
 
+`row_gap` controls the blank terminal rows between entries, independently for the Agent and Space panels. It defaults to `0`, which packs entries together; set it to `1` to restore the previous spacing. It does not add spacing between the content lines declared in `rows`. Consecutive indented worktree children remain packed as one Space group.
