@Raul, Speculating… I’m pretty sure that adapting renoise.Viewbuilder is among the more simple tasks technically, compared to the rest of the renoise GUI + bitmaps. Some of the controls are already close to scalable (apart from their labels), and it would just be a simple matter of multiplying widths and heights with the scaling factor.
Just guessing, I can imagine that Viewbuilder is slightly more sensibly/simply structured (and thereby more easily adaptable) compared to the rest of the GUI. Scaling tools shouldn’t be such a big deal (?).
You know that any detail can return an error in a tool, any change can convert an GUI of the tool with an unsuitable appearance.And, if the tool uses icons or background images, it will need to be updated.Technically it may not be a problem, but something happened to Taktik to make it parked, I am speculating according to your comments.
In fact, if with ViewBuilder we had the ability to resize and type fonts, we could already build tools with scalable GUI, an x2, x3, x4 …Maybe using a multiplier would suffice.
