Problem: browsing large pic collections (> hundreds or even thousand of pics):

I use a AOC e2725Vh screen with 27" size. This is not "small", maybe somewhat above average screen sizes.

In digiKam (KDE?), it is possible to see 5 to 6 pics horizontally and 3 pics vertically, therefore 15 to 18 pics, max at acceptable sizes. 

Question: is there a workflow for how to browse/ assort/ select/ arrange large mounts of pics? There are tags, stars, and many other criteria of course.

A tool for automatic sharpness-detection would be here very advantegous, additionally. This could provide "sharp" or "unsharp" as an additional filter.

- How can I use set-algebra with pics? 
(select= good, deselect= less good, and use restrictions subsequently)

- What is  a "best practise" for browsing large pic numbers? 
- Can someone  advice? 

- Is there a workflow-description for browsing and subsequent selection of pictures?  

Reproducible: Always

Steps to Reproduce:
1. just work with large amounts of pics
2. how do do selection process efficiently?
3. how to selct sets and refine subsets (and so on?)
Actual Results:  
at the given time, such a selection procedure is very inefficient- no screen has enough size, subsequent subsets selection are not supportet (as much as I know)

Expected Results:  
efficient workflow, at least as good as competitive prgs  ;.-)!

it is a "seroius wish", not bug(?)
