One aspect of Cathode that could still definitely be improved is the "Environment".
For starters, there appears to be a bug so any picture you drag to the Environment window is NOT saved/remembered the next time you open Cathode. (In the previous version, no picture other than the default one would appear at all.)
But the main issue is to do with not being able to control the prominence of the background image, the 'reflection'. Basically, if you want to keep the screen fairly dark (transparency very low or zero), as I imagine many would, there is no way to make the "reflection" beneath more conspicuous. Unless you spoil the setting by cranking up the brightness which doesn't look nice. There ought to be some sort of more straightforward opacity control so that the user can have the image's visibility dialled up or down in prominence to taste, independent of "lighting" control.
Also, and I've said it before so why not again, support for the following in future updates would be nice too:
- Special characters (or at least some as would be supported in the regular Terminal)
- Tabs (impure I know) and Vertical Split Panes
- Window appears in the position you last had it (and probably always have it!) and not just that default center
- If there can be reflections, perhaps there could be animated backgrounds (.qtz, .saver files etc)
