Why do I have the impression that something like this existed at some point? Did it?
The Tool Updater and UpdateChecker tools are both bundled with Renoise, so yes.
They’re tools, so not native of course - but if it acts like one and feels like one…
It would. I sent a message to danoise to ask why renoise-team-made tools are not built-in
Few third party tools should be there as well.
Yes, and let me answer here as well: I agree that some tools are really useful, but few are useful to everyone.
There are several niche tools, also among the Renoise Team ones (e.g. Duplex).
Worse still, if they were bundled you would have out-of-date tools being shipped. Personally, I would find that annoying.
