Puts a More row at the end of the sidebar main panel list and lets you decide, entry by entry, which panels stay visible and which move into it: a menu lists every entry with a one-click switch in either direction, a search box filters long lists, and a single Restore all clears both kinds of key. Also hides the footer action buttons, keeps the plugins entry un-collapsible, and writes each choice to the profile config so it survives a restart.
