WorkBench for VB is a VB6 Addin, that makes your bookmarks and breakpoints
persistent! Your points of interest are restored when you switch projects,
restart VB or even return from a crash!

Bonus: Install WorkBench for VB, and you will get keyboard shortcuts for
Bookmark operations: F11 toggles Bookmarks and CTRL+SHIFT+F11 will reset
all your bookmarks.
