Currently, with the "Files and Folders" plugin, users can choose which folders should be indexed by Gnome-do. However, there is no way to specify which files and folders should be *ignored*.
This is important for people who, like me, has a couple of huge folders (over 50000 items) whose files have meaningless names. In my case, these are the frames of many video files, which I must save as images for faster processing in scientific computing packages -- but for other people these may be pictures downloaded directly from their camera (which usually have names like ABC0011234.jpg). Having these files indexed takes a lot of processing (my processor was at 50% for a few *minutes*), and since their names are meaningless, they are not going to be called directly in Gnome-do anyway.
If my hierarchy is like this:
home
-- john
---- work
------ important
------ stuff
------ that
------ should
------ be
------ indexed
------ ...
------ ignore_me
Right now, users have to tell gnome-do to index each subfolder in /home/john/work individually, and then omit "ignore_me" from the list. It would be much easier if they could just tell Gnome do to index /home/john/work, and to ignore /home/john/work/ignore_me
This feature is implemented in the 0.7.95 release, I believe. Feel free to reopen if it is not.
