SUMMARY
When you create new brush presets, you can't tag them. The dialog is missing the necessary tagging feature. This causes the brush preset to disappear in a longer list of brush presets


STEPS TO REPRODUCE
1. Open the brush engine with f5
2. Save a new preset 
3. You won't see any option or drop down menu allowing you to tag your new preset

OBSERVED RESULT
Creating new brush presets from scratch is straightforward but the save dialog there is missing a pop-up to specify a desired brush preset tag (if available of course, usually there are some by default as well)

EXPECTED RESULT
In absence of a tagging choice from the user, the new brush preset should inherit the tag of the currently selected brush preset tag as specified in the brush presets docker or,
if “all” is selected, add a new tag like “new”, so that we aren’t confused where to look for new presets because these orphan presets get mixed together with the tagged presets. A mess in short.
