How to make toolbar changes stick?

[onefish]

G'day, hope someone can help with this. I am using Windows 10 on a couple HD 10.1" touchscreen tablets and I've been searching everywhere for a video player that:
1) will play all videos
2) has controls that are large enough to use on the touch screens
3) saves playback position
4) supports gestures (nice but not critical if buttons are big enough to be used)

I have used VLC for many years on my desktop but the control buttons are about 3mm (1/8") on these tablets and unuseable. I tried MPC-BE also but same issue.

I thought I found the solution in SMPlayer. It allows me to increase the icon size from default 40 to 100 which makes the control buttons just about finger sized, perfect. Only every time I close the application the toolbar changes are not saved. They remain for the open session but are reverted to default in the next session. I tried removing all the icons and replacing them with icon size 100 selected but same thing happens.

Is there some trick to getting the toolbar changes to stick?

Cheers!

This problem occurs with the H2O theme, because this theme uses a fixed size for the icons. If you select another icon theme you will be able to change the size of the icons.

If you want to use the H2O theme with a different size for the icons then you need to edit the file style.qss (in the themes/H2O folder) and change the "qproperty-iconSize" lines.

rvm, thank you so much! I originally went through all the icon sets and determined that the the default H2O was by far the best looking. It took me a couple of tries to work out which qproperty-iconsize entries to change but got it now. I didn't want to increase the top toolbar icon size, just the control toolbar and floating control toolbar. These are the middle 2 occurrences of qproperty-iconsize in the file if it helps anyone else (there were 4 occurrences in my h2o.qss file).
