Image browser command bar : filtering and sorting improvement


  1. Allow filtering by file extension on Windows
  2. More generally filtering using regular expressions on filenames and path names

Multi-criteria sorting, for example:

  1. date picture taken, descending
  2. file name, ascending
  3. file type: raw, dng, tif, jpg

Allow to consider as equivalent: jpg, jpeg, JPG and JPEG
Allow to consider as equivalent: tif, tiff, TIFand TIFF
Allow to consider as equivalent: dng, DNG

I would also like to use base regular expressions like OR, AND, NOT. Could be used for e.g. find 1 star or 2 star etc; or find 1 star and not tag berlin.

In addition, a search for green or red dotted pictures would also be great.
