1. Add one menu item "Close All But Pinned" to the right-click menu.
2. Improve the "Editor Bookmarks" function, now the Description column is an input-text type, but sometime we want to input one than one line desc, so it's better to show a text-area by double-click one Bookmark, or provide a icon ( ro a button with "...") to trigger to edit the Bookmark.
3. The most desired functions is: there' s no way to highlighting comments/notes in source code like "//todo:", you know, sometimes we want to add some important comments/notes displayed highlighting in source code. I suggest to add a tag name "//note:" or /note ... note/, and it can be added to "Colors&Fonts"->"Custom"
