I personally find myself rotating objects by 45 or 90 degrees very often. Usig the rotation dialog and moving the handles/typing in numbers is rather cumbersome when there are many objects.
Therefore I would love a way to quickly rotate things on the build plate, either via right-click or as a small icon/dropdown/whatever somewhere near/in the rotate interface. And/or possibly integrate a keyboard shortcut to rotate object by 90 degrees (maybe 45 when holding a modificator key like shift). This would actually save really a lot of time, every rotation takes at least a few seconds to do and it does add up quickly.
You can use PGUP or PGDOWN
OH lol. Thank you so much.
Ok @Bambu please just document stuff like this properly, this one is missing as far as I can see
