I share your love of BibMod's simple, but effective customization and I, too, could not live without it under any circumstances. So, it is with great happiness that I present to you the solution to your problem.
The Insomniax Recompilation includes a version of BibToolbars (sorry, no BibWindowMods) which has all the features of the original and more (such as a bigger, better XP bar). Plus, it has prettier textures
. It is updated inside the Recompilation every time it breaks, but it has never been released individually to mod sites for some reason. I have included a ZIP with the latest version in this post.
The author of Insomniax has included some nice extra options, so try typing " /bibmod " in-game.
