About all the "skinnable" which i was reading about through tons of topics over the past few months...
Really?
Is it so important for you to have a colored/darker or black background?
90% of all softwares have got a white background, so we're all used to it.
If it's to bright for you at night, adjust your monitor. Or invert your screen colors if you can't live without it.
........
But skinnable is just a waste of time.
If the skin of Construct is your only problem... /sigh
Well, not real important, but a preference. I use Photoshop every day and it doesn't have any white backgrounds - and I'm used to It. I use C2 every day and it has white backgrounds - and I'm used to it. But I definitely prefer Photoshop gui.
I couldn't care two hoots about Mac, or Linux, but C3 is going to support that audience.
Since the IDE is receiving a massive overhaul, you need to get it right from the ground up.
