It would be great if you could edit the attributes in the attribute editor/channel box more easily and especially more user friendly for artists that don't know any coding.
Wouldnt it be great if you could type '*2' instead of '*=2'?
The sames goes for any other math operation.
Additionally it would be great if you could type 'pi', 'e' and 'g' for each constant.
Furthermore it may be great to type for example '2k' for '2000'.
Hope you like the ideas.
