Well, you already can rename plugins in Renoise. If you want them to show up as first plugs, simply name them to “.MyPlugins:Plugin” or “.Favorites:Plugin” (or whatever with a “.” prefix).
I would quite like it to display by effect type (also for instruments I guess) but this would require renaming every single one. A way to view by file structure could help with this, although at the moment mine isn’t sorted at all as I only really use Renoise and it doesn’t benefit from doing so…
since LADSPA plugins are effects, not instruments, the workaround would be less effective because, although you can save DSP chains using the Disk Operations panel as XRNT files, loading an XRNT file will overwrite the curerntly present DSP chain. So taktik’s suggestion is surely better in your case
It would be even more wonderful if it was possible to export and import the renaming. I use 3 systems and I’d have to do all the renaming 3 times if I wanted to organize my plugins. Also, when I reinstall I have to do all the renaming again.
That is simply a matter of copying the CachedVSTs.db database from your “…\application data\renoise\v[versionnumber]” folder to the same folder on your other systems. Considering the idea you have all the same amount of plugins on each system and each system is has the same platform. (meaning is at least all windows or all Mac or all Linux, regardless of the edition)
