Description Blair Noctis 2024-07-14 11:22:49 UTC 
SUMMARY

When configuring history size of the clipboard, I can only find out by trial and error that it has an upper limit of 2048 entries. It's not shown anywhere in the UI, nor in Help (Documentation not Found).

STEPS TO REPRODUCE
1. Open clipboard configuration
2. Try to enter a number larger than 2048
3. Use Arrow Up key to scroll it to the upper limit

OBSERVED RESULT

As in SUMMARY.

EXPECTED RESULT

David Edmundson expressed their opinion that a limit beyond 2048 "is ridiculous": https://bugs.kde.org/show_bug.cgi?id=446112
Although it seems arbitrary, I don't want to argue for that here, but the UI should indicate as such, e.g. "(max 2048)" after the input box, ideally with a reason.

Also, there should be documentation (ideally, I understand hands are limited; or is it too simple to be worth writing one for?), and its configuration should probably go into System Settings.

Out of curiosity, what do you need this for? If you just enter a super duper large number like 9999999 into the input box, it'll automatically go down to the maximum value

No? I tried that (the first try, actually, and multiple subsequent ones) and it just "stuck" at the first "impossible" digit.

This wouldn't be "needed" if "automatically go down to the maximum" actually worked. But it's always good UI to let the user know of maximum/minimum values without trial and error in the first place.

Sadly, it does not. I'm setting this to confirmed, as it is a valid issue, just of very low impact.

I've just checked another combo box in Settings > Sound > Configure Volume Controls and that snaps back to 100% if you try to enter a value higher than 100%.

So this is a consistency issue as well.
