Accessibility fixes
First up, a quick comment to say I love what you've done here. As someone who has used wave editors for years (fondly remember Steinberg Wavelab but currently limited to using Audacity on the Mac), I really like this tool. It works very nicely and I will aim to use this now instead of Audacity and will probably have some suggestions for things I'd like to see.
One thing that I can see is that there are accessibility issues here with the app, primarily:
- Keyboard-operability
- Low contrast elements
The good news is that I work in the field of accessibility and am happy to put in some fixes for this (it's a pleasure to be able to contribute to something that I know I will use and also be able to open this up fully to a wider audience).
Anyway, just a heads-up to let you know that I will be putting together a pull request soon to address some of these issues for you :)
