I would find it handy to have brush widths persisted on a "per tool" basis. For instance, if one were to work with the paint brush tool, and set it to a width of 5, then switched to the line tool and set it to a width of 10, when switching back to the paint brush tool it would be nice to see the brush width switch back to 5.
(Sorry if this is a feature has already been requested, but I couldn't seem to find it by searching the forum, or by reading the commonly requested features post.)
Thanks.
