I completely agree. The brush studio seems flawed in its implementation -- at least to Procreate where you can much more easily see what brush you are using.
As noted when using Brush Studio
1. Select Brush -- it is highlighted
2. Change any setting such size -- it is no longer highlighted
3. Return settings to original -- still does not highlight
4. Brush Name Not Shown -- it also hard to know since you cannot remember a name, unless, as noted, you go and fuss with the advanced dialogs for the brush. Hovering will show the name, but as I am using a Wacom Cintiq this is agonizing hard to do.
I find this exceedingly frustrating as I am doing digital art. Makes me want to look at other programs to see if they are better suited to digital art workflows. My hope with Affinity is a single product between macOS and iOS ... but even something as "trivial" as this is a huge amount of friction to me -- especially as is only one of 3 studios I really care about: 1) brushes, 2) layers, 3) colors.
