I bit the bullet and installed 2.5.0 master branch; very impressive improvements:
- The search in map view works again; hooray!
- funky colours in the dialog boxes; I guess I can tweak to my taste with the .css
- I especially like the improvements I have noticed to collect images:
** the count of image numbers in parentheses no matter which filter is used
** the hierarchy in date/time filters; very nice indeed.
Hats off to the contributors.
