After using krita for a few days ,I really love this software,but I want to give suggestion to make it better!!

1 Erase brush should be easy to recognise when change brush mode.
I like to draw in a full window mode ,when I press "E" to change to erase brush ,it's the same icon to normal brush mode ,
sometimes it's hard for me to know whether I'm using brush or erase...

2 After rotating canvas can't return it to normal
I use shift + mid mouse button to rotate to canvas ,but I can't find a way to rotate it back to normal, cause I don't know how much
degree I rotate it and the "Rotate Image" function can't help me to get it done!!

Press '5' to reset the rotation.

As for 1) a programmer/user noticed the same thing, so the eraser mode is far more obvious in 2.9 alpha.
