There's a small bug with the colorizing screen in WB6. This probably goes in line with my other complaint about NEEDING to actually be able to hit APPLY on those screens before WB6 saves the settings as apposed to "auto/live saving" which is kind of stupid and there's no reason for it. Anyway, if you use coloring HSL stuff you can change the colors and then drag the color bars to pick a color, but you actually have to hit APPLY to actually color the skin with the new choice. Well, guess what, because of the "auto/live save" that WB6 does on the config screen it saves and keeps each and every click and change, but it doesn't auto/live apply the color you pick. This causes a problem if you're just messing with the color, but don't want to apply it. Normally, you could just close out of a program or hit cancel and then it WON'T save the changes. WB6 won't work like this so even though you didn't click on APPLY to actually change the color of the screen, the color bars won't go back to the "currently applied" color so you loose your place on the specific color you just picked.
So in closing, TAKE THE AUTOSAVE FEATURE OUT OF WB6 CONFIG... IT'S JUST CAUSING ISSUES LIKE THIS AND IT'S REALLY NOT NEEDED.
Thanks!
edit: One more thing. The color choices are not saved "per skin". So, if you choose to change color on one skin and apply another skin, if the color you changed happes to match on the new skin the same color changes apply. Kinda silly don't you think? How about an "auto reset/disable" to color screen if you change skins? Also, I'd like a reset button to ALL the color bars like you have for skin brightness. It just makes sense. If you mess up or want to go back to defaults you can simply choose reset and "boom", back to the starting point it goes.
