Adding folders with too many images froze the windows
Created by: vjj
When adding folders (with the new recursive search - that works fantastically) with too many images, froze the windows (File open dialogue and preferences window) while it adds the images. Currently File Open dialougue remains open while adding the images but not responding to inputs and it looks like the extension crashed, though it is working fine.
It will be better if we can close the 'File Open' window immediately after selecting the folder and then (like your fix in another bug) asynchronously add the images (and may be add a gtkspinner in the preferences window).
