Thanks for reporting the draw brush radius issue. It should be fixed in today's update.
Handy, but I would like to be able to add the different nested selection methods instead of just the box. In Grease Pencil I use the lasso far more than the box. I suppose this should be true for all of the nested tools, but the limitation of only the select box is what immediately jumped out at me. Thanks for making this wonderful add-on.
It was an omission indeed, thanks for pointing that out. I've added all the nested tools in Edit mode. You can enable them in the add-on preferences.
Absolutely loved it, except it had a bug that forced me to disable it. Every time I would activate the tool it would change my pen's radius size. Fixing the radius costed me more time than the tool saved. I'll turn it back on as soon as it's fixed.
