Useability of thumb size slider no good for higher values

Post by klaus2 » Thu Aug 18, 2016 7:40 pm

I don't know if it is really a bug (don't think so) or a enhancement report. so i place it here.

In "2 small suggestions" in http://newsgroup.xnview.com/viewtopic.php?f=60&t=33608 i mentioned an easier access to the iteration steps of the dropdown list "thumbnail size", for example by a keystroke "+ or -).

Alternatively yuo might use the thumbnail size slider on the right side of the browser.
I try to explain here why in my eyes it does not behave very good:
The more you shift the slider to the right side (increasing the thumbnail size), the more you can see that:
the proportionality of the size of the thumbnails container panels and the real thumbs sizes come out of sync
(= the thumbnails are too small now and do not cover the the size of the container panels in an economical way).
Yes, MP tries to correct that after the slider shift operation, but the result is no good.
The dropdown list "thumbnail size" iterations are using the space economy much better, but it is not so easy to access these iterations by keystrokes.
Result:
- better behaviour when using the dropdown list iterations, but not so easy to access
- not so good behaviour of the slider, but it is easy to access.

Is that a bad idea?

My impression is that there is no reasonalbe proportionality between the thumb's container panel sizes and the thumb's sizes itself,
given you shift the slider position above an iiteration value higher than, let's say somehow, 30-40 percent.

So, for normal cases (different use cases might exist), a higher slider value (40% to 100%) simple leads to wasted space
and is useless in my eyes.

Idea: allow an optional parameter overriding the slider's maximum value to restrict it to a reasonable limit.
By that the range that is really used (beyound ca. 40 percent) might be spreaded and, so, used more efficiently.
eg. thumbsize_slider_max_restriction=40

Hi, klaus2. Isn't that what the button next to the slider (Click to change between width of thumbnail and number of thumbnails per row) does?

Oh wow, indeed i really didn't realize this button yet; obviously it alterneates between two positions
and i find it to be useful :-)

However, if you test by shifting the slider to the 70 percent position and see the effect, at least for video files,
do you find the effect is really intended?
(imo at least not for video files, because their thumbs cannot exceed certain size)
