640	Rapid access file history can slow startup checking if files exist	Tom Goddard	Tom Goddard	"The current file history code checks all the files in the history to see if they have been deleted before showing the icons.  With 200 files (current history size limit) this can be time consuming.  I have an external USB drive with some data files I opened that are in the history and I believe this drive sleeps and can take a couple seconds to spin up to speed, slowing the ChimeraX startup so it takes 3 or 4 seconds.

For maximum startup speed we should probably not remove the file history entries until the user clicks on one, where we can bring up a dialog and asking of all missing files should be removed from the history.  This is what Chimera 1 does I think."	enhancement	closed	major		Core		fixed		pett@…				all	ChimeraX
