Currently, if a plugin wasn’t found on the system, there seems to be no indicator in the instrument list that it actually is a non working instrument slot. What about using an additional icon for not loaded/incomplete instruments? For example, instead of that chain symbol, it could be a symvol indicating that something really is broken a lot.
I know this might sound like a tiny detail, but I actually believe that Renoise’s workflow could be improved by a lot, simply by adding such tiny comfort stuff. Also doesn’t seem to hurt to implement, from an effort-wise perspective.
Also the not found fx plugins could be outlined in red in the mixer or something. I guess there already is such a color type in the color scheme defined. At least in my color profile, I hardly can see the not found fx plugins in the mixer view…
