Oh I see! I just thought Antonio was the right man, so I was a bit impatient hehe.

@Antonio Vazquez (antoniov) for the tools I can add icons after the merge. For the sorting, why do we need icons here? IMO the sorting may be hard to convey in icons, but easy with text.

I can confirm the issue.

@ Dani Fraudling (El_Fraudo) Please don't assign yourself the task, only developers must do that.

@William Reynish (billreynish) We would need several icons for these patch:

I won't review this in detail, but broadly this seems fine design-wise, really nice improvements.

There are a lot of files affected in this patch, but a lot of the changes are related to the full function naming cleanup, specially in BKE_gpencil.c module. After this patch will be merged in master, I'm going to split gpencil.c file, putting geometry functions in gpencil_geom.c, but I didn't do that in this patch to avoid more lines.

I can confirm this.

I will manage this task in the refactor. In that change, the eraser never will create frames, only draw will create frames. The change will applied when the refactor patch will be merged in master.

Seriously? You know you are changing the current active editor to 3D View with that, right? You cannot, absolutely cannot, do that in a py script and expect things to work... UI will simply not update quickly enough, and you'll call the transform operator with a completely broken context.

This is equals in 2.79, 2.80 and 2.81, so we cannot consider it as bug but as ToDo. What is actually missing is update the active channel in the Dopesheet.

@Sybren A. Stüvel (sybren) This is a very old report, so not sure is valid now. Anyway, we would need more artist feedback to know if we must limit frame creation with eraser.

This is not a bug. Due the refactor that we are doing in the drawing engine, the anti-aliasing support has been removed temporarily. As soon we integrate the refactored engine the smooth lines will back, even with better quality.

Was the same issue as T67805: Mouse pointer doesn't update when changing tools via shortcut or pop up menu after all.

T71164 is not the same bug.

This has been reported before, see T67805: Mouse pointer doesn't update when changing tools via shortcut or pop up menu (or T71164: Annotation Tool Cursor not properly Showing/Updating.), will merge these reports...

I just fixed it rBfffb185dbffa

Setting as high because all grease pencil and annotation objects are broken.

Ahhhhh gees now that ones worth writing home about isn't it.
