Is there a dark mode to save my eyes? If not, can I put this in as a future feature request?
There is no such mode currently and is unlikely to be added to the current interface. However, it's likely that sometime in the not-too-distant future there will be a total overhaul of the desktop software UI, at which point dark mode could reasonably (much more easily!) be added.
Thanks for the suggestion, I think that is a great idea.
