GTK little probe screen

I am working on modification of Probe Screen by Serguei Glavatski (c) 2015
This modification moved the icons from one window to containers with switchable vertical tabs.





 







I have a control panel made on the machine.
Unfortunately, I have a display with a low resolution.
So I have to save space on the screen. That's why I used switchable vertical tabs.

At the moment, the Gmoccapy screen is huge, because there is a bug:

What do you think about GTK little probe?

I'm using an old version for modification, if you're interested in the current version, check here:
- vers.ge/en/blog/useful-articles/probe-screen-v28
- github.com/verser-git/probe_screen_v2.9 

Little probe screen was added to master branch.

I will be happy for feedback.
