Brush size slider behaviour

Changing some parameters like the brush size for the object selection is unprecise. Depending on the screen solution the maximum value can be 4000 and even more - then it get’s really complicate to change the brush size from 50 to 55 or so.
I recommend to think about two options for all sliders (which should be easily toggled on/off):

  1. logarithmic / decimal scaling
  2. snap feature which would for instance select preferentially values 5,10,15,20,… between 0 and 100 and 110,120 and so on up to 500 and then 550,600,650, etc.

The size can be changed by clicking on the actual number and entering a new value, but when already using the keyboard for changing a value why no keyboard shortcut is available for doing so.
