The 'yellow snake' icon (nice analogy

) - which is the standard glyph for bookmark/category - shows that "something" is imported. If nothing appears, please do like this: Close the program, hide/rename the databases and restart the program. Does it work now?
m.Th., many thanks for your guidance!
Indeed hiding the databases caused XnView to rebuild it with default settings, and now when I read each folder, it populates categories based on keywords included in files - great!
As I start to understand what is happening, but still have fresh view, I noticed some issues/have wishes - where should I report them?
My findings:
1&2. The cause of the whole affair:
sub-catergories produced automatically from keywords are based in category 'Other' in the default tree. When 'Clear All' executed and consecutive 'Update database from files' requested, nothing is assigned as parent node ('Other') is missing. I believe the keywords should be imported to the root: 1 - it will let refreshing/rebuilding the dictionary in cases like that; 2 - it will not cast hierarchy by default
3. The reason I could not delete catergories one by one and used 'kill'em all' option appears to be invoking rightclick (for actions pop-up menu) with
ctrl, rather than Mac default
cmd. (I blame Apple, but their rule is still a rule...). At the same time, the option button next to search window on the top of 'Categories' panel requires cmd for rightclick (so Apple-correctly)
4. The same (ctrl, not cmd to produce rightclick) issue in 'Categories filter' panel for categories action pop-up and worst of all - on the thumbnails in the main panel.
5. Categories based on keywords are imported at first file read (they appear in categories tree), but the yellow snake tongue only appears on the tumbnail after first filtering using 'Categories filter' panel
6. When category applied/removed in 'Categories' panel (by ticking/unticking), the marker only appears/disappears when another file selected (not immediately when toggled).
7. When category applied from action menu on the tumbnail, the marker appears immediately (so as should be in the above), but it would be nice to be able to toggle category on/off from that menu (it is one way only now, so any mistakes require going to the 'Categories' panel)
8. In 'Categories filter' ratings and colour labels expand every time XnView restarts, even if collapsed before closing. Categories on the other hand start collapsed, even if left expanded. Can the status be saved?
9. Any chance to change/set default zoom level of Google maps (in image Properies > GPS). 'Open GPS location in Google Maps' (and maybe Bing Maps?) menu option (on top of already offered Google Earth and GeoHack) would be nice
That's it (for now

) I'll carry on with organization.
