can I match strokes with this tool?

[Hifilo]

I was using the Gpencil & noticed there isn't anyway to change brushes. Your tool seems to address this by allowing further refinement of the strokes which is very useful(I can't believe there's no way to natively change brushes after you create them).

If I have 20 or 30 frames, is there a way to make changes to one of them, and somehow apply the same thing to others? Does your tool have a way to match properties? ie. grab the properties from an existing stroke, and then apply it to another?

Hi,
It's True that there is an easy misconception about the brush system in grease pencil.
A brush is just something that define how stroke and points are created, at the moment they are created (with or without an attached materials).
That's it !
So once strokes are created it's done, there is no more relation to the brush, and you have to go through edit mode, sculpt or scripts. Hence my (not so) little Refine_stroke addon ^^.
The idea was indeed to allow some precise post-drawing modification.

About your multiple frame thing. I don't have any tool to replicate a change (I don't have a "match properties" feature).
But you should just apply your change on all drawing at the same time.
Select your 30 keys, go into edit mode, enable multiframe and select all needed stroke before using a tool.
Most of features in the addon are compatible with multiframe.

Hope this helps.
