True Launch Bar v6.6.5 beta

Plugins do work now. However, I am finding another problem. I don't see "Background Transparency" working at all. Shifting from Opaque to Transparent has no effect on any skin. Is this a bug?

I guess you want to change the toolbar transparency. You have to open TLB Settings and set the transparency in Toolbar->Appearance (see the attached screenshot).

The "Background Transparency" in the Toolbar Properties works for toolbar background defined in "TLB Settings->Toolbar->Colors and Fonts" and for toolbar overlay image.

Also, can we get a white-lettered version of Uptime plugin? There is only black and hard to read on black toolbar

The "Digital White" is pre-installed. Also you can find some skins in the skins library.
