Pinta daily PPA on Ubuntu 14.04.
1. Start Pinta (if opened then close/start it).
2. Click on Line tool and look at Arrow checkboxes, by default 1 and 2 checkboxes are unchecked and no preferences for Size, Angle and Length are displayed.
3. Click on Arrow 2 checkbox and now three additional drop-down boxes appears (Size, Angle and Length).
4. Click on Text button and type some text on canvas.
5. Click on Line tool and Arrow 1 and 2 are unchecked, but all three drop-down boxes are still displayed.
This is strange, because it is not clear to which arrow (1 or 2) this settings belongs to. In my humble opinion one of two should happen:
a) Arrow 2 checkbox check should be preserved (I like this one).
b) Arrow 2 checkbox should be unchecked, but also Size, Angle and Lenght drop-down boxes hidden.
I see 5a) was implemented. I remember reporting this problem to Andrew during GSoC and he fixed it. Now looks after several months I still see this bug reported opened. Tested on Pinta development 1.6.0.62 on Windows and problem is fixed.
I am marking this bug as Fix Committed.
