Hey! I definitely want to add keyboard shortcuts and those will be added in the future.
@Direct, thx so much for your answer. u can check out how IL Wave Candy plugin handles the freeze toggle. Besides adding a shortcut, their approach is really inspiring and efficient like when you hold Ctrl + left click on the spectrogram it freezes, and pressing again unfreezes. Super smooth workflow tbh. So imo, having something similar here, along with shortcut support, will make the feature way more practical, especially for transcribing where the easier and faster the tools are, the better.
Right now the behavior of holding left mouse shows the coordinate values (hz, tone, time). I think it will be more intuitive if those values just showed up on hover, since they’re always useful, instead of needing to hold the mouse button. Again, I’m pointing at Wave Candy because their behavior feels more natural and intuitive. So yeah, to recap:
add shortcut support for toggle freeze
add a Ctrl + left click toggle freeze option
make hovering with mouse show coordinates by default instead of needing to hold left mouse
 
Anyways, if you ever open source the code I will be glad to help, I could even reverse engineer and add the toggle freeze feature myself, but tbh I prefer it be done officially. Anyawys, amazing product and thanks for all.
