When I can't see boundaries properly I just move it around until it is over the galaxy in the background. Makes it much easier to distinguish where the boundaries are.
I used to be able to do that and call it "sufficient" but in recent years my vision problems have worsened enough that the action you mentioned is no longer good enough.
I already wear corrective lenses and they do not help this problem; it's not a simple "sharpness" issue. Brightening my monitor enough to make the overly-dark built-in background light enough now makes the hull sprite(s) themselves much
too bright.
Also, the constant panning of the hull sprites I'm working with over the less dark galaxy graphic is adding up to a huge waste of time that I'd prefer to spend on
actually making the ships instead of wrestling with the problematic existing background of SF-Edit.
If Trylobot makes the suggested change to his ship editor, I'd most probably manually insert a solid image of continuous, medium-brightness neutral gray as tprogram's background (or whatever type of image choice helps with my sub-par vision). Or maybe something similar, but instead with a subtle repeating pattern like slightly lighter /darker gridlines or etc., idk
Oh! That reminds me:
Trylobot, would you please also grant users the ability to change - while the program's running - the color (currently pure white) of all the onscreen UI/help/instructions/weapon slot type/etc.
text in SF-Edit?
Just some sort of simple RGB 0-255 color picker with a small, real-time preview swatch showing the user's currently-selected text color, and another swatch for the proposed new value, plus a Commit or Save command for the feature, would go a long way to help people with less than great vision. It would be super-helpful if I could harmonize the text color with whatever user-selected background image I end up dropping into the program, as well as harmonize it with the majority color/brightness of the hull sprite I was currently working on.
Thanks in advance for considering this request
