I had heard explorer window transparency (background, not title or navigation bar) was planned to be added down the line for WB10. Is this present in the new beta (i'm reluctant to test it out myself as I'm not a skin author and with the report of many skins being broken by the update) or is this gonna remain a pipe-dream. I know of so many awesome blinds I use that look even better on prior versions of Windows and the old WindowBlinds due to this extra transparency effect.
Obviously fixing issues should take precedence but we should always be looking forward also.
Also, recent stable release has seemed to add support for theming the explorer ribbon yet I have noticed this being rather sporadic and sometimes elements returning to default colour scheme. I am not certain whether this is a conflict with another ObjectDesktop software such as WindowFX or a bug but I'd be interested to know if this issue is still observed in the beta.
