[digiKam-users] Changes in the label type Pick or Color are not immediately recognized by filters

[2895qgvg6v at liamekaens.com]

I asked a similar question 1.5 years ago 
(https://mail.kde.org/pipermail/digikam-users/2020-August/031169.html), 
and got got some suggested workarounds.  When I learned that it worked 
for star ratings but not for pick labels and colors, my guess was that 
it was an accident (or bug) the the behavior was missing, but I never 
got a definitive answer about whether the behavior is intentional or not.

I agree with you that it would be great if images immediately 
disappeared from view when their pick label or color change to a value 
excluded by the filters.  In fact, this is the top issue preventing me 
from switching to digikam (from Lightroom) as my image management software.

Since I've had a long career as a software developer (although I'm not 
familiar with KDE and the QT), I was thinking I would like to contribute 
to digikam development, so I spent some time in late 2021 creating an 
environment to build digikam locally.  I then tried to read the code and 
trace through it in the debugger to figure out why/how images 
immediately disappear when their star rating changes, with the hope that 
I could make it also work for pick labels and colors.  I did get some 
understanding of the behavior, and saw some differences between the star 
rating and pick label code that looked like it might explain the 
difference in behavior, but I didn't get the pick label code working.  
Unfortunately other things took priority, so I haven't worked on it in 
2022.  I'm hoping to get back to it later this year, but there have been 
two releases (7.5.0 and 7.6.0) since then that include major changes, so 
I'll probably have to start from scratch.
