Make sense to freeze the features and get on with the process of developing. If features get pushed to the next sprint(etc) then that is a function of users getting feedback quicker and being more precise and measured in their expectations. Let the development process take place at it’s current pace, and then be happy that there is a process to develop that can be built upon.
Possibly focus in on a higher level within the development process and use this feature ‘cull’ / line in the sand as an opportunity to better think through how features get importance placed against them by a skilled audience, maybe a simple star rating and listing that give greater visibility that has discussion attached so the thread of thinking can be followed more readily from both the user perspective and from the developers perspectives. (line up can do this easily)
Valentina have just moved to this new forum platform, so perhaps use this new mechanism/space to support wider connected input, earlier and with indepth feedback. I suppose what I am suggesting is treat this as a solid learning curve as you transition into smoothing out features relative to development cycle improvements, and then accept cut off points as opportunities. This could be a point (new forum) to widen out the discussion on notches and to also get some overview on the technical difficultly, and resource commitment needed to achieve that goal. Transparency.
Ref: notches, I have to disagree here as to how critical these are at this point. Technically notches are based on line lengths that match between patterns - these are typically set at nodes or a change in linetype geometry. The current drafting allows for this ) In other words they technically can be set in a next workflow if moving to CNC cutting - and if printing it’s not too hard to align pattern pieces untill this feature comes on stream. If one uses the current output, they can simply apply a notch insertion point on a change in line type geometry (node) - for example in inkscape this can be done on a seperate layer assigned to CNC cut layer by inserting a symbol.
If the notch is simply for visual reference, then I fail to see the need at this point unless it is tied to full line length between notches. Notches need to be well considered in the wider spectrum of geometrical integrity, how they get passed on in terms of machine data language.
