Here are a few things I've thought of that could be cool:
- Multiband (4 bands is probably enough)
- EBU metering (LUFS)
- Resizable window with more useful visualization
- New distortion modes
- Threshold for even more gain capability
- Mid/Side processing
So, I'm wondering if any of these seem redundant or pointless, especially the metering aspect, as there are so many good meters out there, and making the meter even remotely competitive with dedicated meters will take a lot of development time.
As with all of my plugins, I try to keep things simple. If there are any features you'd add/remove here, let me know. This is a chance to influence the future of the product, because honestly, I can't pretend to know what's best for everyone - and I also don't want to fix what isn't broken.
