This is a Tint2 theme made to match the Nooto Fluxbox theme's taskbar (for original theme, see here: https://www.opendesktop.org/p/1016938/)
I generally prefer Fluxbox to Openbox, but it seems to be bitrotting, and Hexchat in particular doesn't work with it any longer, at least on my system. But I love Nooto and have been using it for years. So what's a girl to do? Clone it in Tint2 of course!
This is a near-perfect replica, but the Workspace area doesn't actually have working switcher buttons (yet: I may add these later if I can figure out how...). The workspaces are actually called < Workspace 1 > and so forth in OBConf to mimic the look of Fluxbox's panel.
You must have the Noto fonts installed for this to work. Yes, Noto for Nooto.
