voxel follow is very nice,
but would be better if you could move out of the sculpt,
i almost like it more then move brush, because its more fluid ( and its pure voxel) but you should have an option for amount of smooth it uses
and the amount of pulling, stronger = pulling longer the same volume
sphere brush VS merge on pen,
i love the freedom of sphere brush, and i would like to do same thing with other forms
but merge on pen feels like your stuck all the time > when hitting borders, it would be cool to have same freebrushing feel
but with other shapes, so you select freesculpt > standard is sphere, and then you select shape, or some optimized choiches
as for presets,
really needs to save brushingtool you working with and the option to show all presets or just the ones for that brush
create own custom set of tools,
if you're sculpting you dont need axial, 2d, cloth, text, ... , it would clear everything up and better focus on what you need
