Hey @jacqueslucke I wanted to chime in regarding this because I´ve been thinking about it lately and I wanted to ask a question.
Will there be a node to “freeze” geometry edits?
I mean, imagine that you enter in edit mode inside an object, then you modify it´s goemetry, then you are happy with it so far and you want some kind of freeze state, but in a “procedural” manner, so you can continue editing and that edit will be stacked over the previous state, and you can repeate the action several times, of course if you remove an intermediate steat things can be broken or not, depending on the edits, but this also allows you to iterate and have different versions of one object, and it also allows you to be sure that you will always have a version of your object in a state were you were happy.
I hope you understand what I mean with this, it is pretty useful, in other packages this is called in different ways, in Maya it´s a group of action nodes , like grouping lal the actions, extrude, move, poke, etc… if you remove those actions you remove your edits, in Max it´s a modifier, the Edit Poly (something that new users that come from Max really miss), in houdini it´s also nodes, and I´m´not sure how is it done in C4D and Modo.
In the end this could be pretty good for poly modelling, and I though this may be possible with “modifiers nodes”
