I''ve just upgraded to 0.48.3.1 and noticed a step backwards in the functionality of erasing.
0.47- used to have a clumsy

that eliminated the whole object at the path of the brush, while the real and more useful erasing options were under a secondary functionality of the

. I.e. we used to erase part of an object (kind of classic use) with Alt+mouseDrag. That in fact was a substract-surface functionality, the complement of the add-surface one under Shift+mouseDrag. Therefore, the bunch of options for calligraphic tool (tremor, wiggle...) was applicable to it, making a very rich feature.
0.48.3.1 improved eraser tool. It looks like we now have the thing in its proper place but they forgot bringing the former options in the move. Funny, now Alt+mouseDrag at calligraphic tool do nothing!, so add-surface functionality lost its counterpart and so we did with all the options we used to have before.
I've never posted to Launchpad, and I just wanted to know your opinion before shouting it out

over there.
Best.
