Personally, I prefer to have the stabilise brush settings as a dropdown below the the button to activate a stability mode as this consolidates the settings close to the canvas. Currently, for mirroring there is already such a dropdown.
It would be interesting to tackle brush stability settings the way they are handled for brush settings:
I thus propose to have these settings in a dropdown too:
Alternatively, considering the discussions on this forum about a UI overhaul that is closer to Blender (which I find visually more pleasing and convenient). There, the dropdowns consolidate all options (so the UI can remain minimal and you won’t need dockers for these settings). Additionally, in Blender, these menus can usually also be opened as a pop-up using a keyboard shortcut.
When drawing/ sketching precise curves it is very important to have the stability settings, try to sketch the curve and then try and change the settings until you manage to get the desired curve.
