I've completed work on replacing several hundred profile images with new higher resolution images. I've also brought back a much requested feature - the dark theme! I've worked hard to create a darker looking theme that doesn't look too hideous. If you'd like to try it out, just head to settings on top right of main window and enable 'Use Dark Theme'. For OLED users wondering, yes, the blacks are indeed #000, so your pixels should be off completely on those areas. I experimented with various colour palettes on the menu bars, but ultimately kept the slate colour for aesthetic reasons.
As always, if you appreciate the work that I put in to these updates, it would be great if you could leave a Play Store rating. They really help me out in terms of future sales, which means I'll be able afford to continue investing in the development of the app.
