I decided this is not something I can live without, so I've updated it for BtS. From my addition to the ReadMe:
-- Mostly rewritten from scratch based on v1.93, may run a little faster
-- Does not include most v2.2 features, or Fitchn's Index, or any customizability or options
-- Does not include a Promotion Upgrades page, would be easy to add but I don't use it myself and was pressed for time
-- Individual panes now follow my own consistent GUI layout and look much better than v1.93 and vanilla
-- Wonders are now seperated into National Wonder and Great Wonder pages, with code to handle linking correctly
-- Back/Forward history now omits category-only selections that don't show an entry in the main area, for faster/better history navigation
-- Keeps the Back/Forward buttons along the bottom as in vanilla, and the title bar is no longer overriden to show selection names
I am not planning to add much more than is already here since this suits my needs as-is, however I will keep it current at the very least (if no one else does).

I didn't/don't know what the Index even is, as I was using an older version (1.93) all the way up til now. I only noticed it in reading Gaurav's ReadMe. I will look into it when I have time; right now I'm still scrambling to update all my stuff so I can *play* BtS. Heh.
The UnitUpgrades screen is a little flappy I know, but I included it anyway b/c I use it, and it's still usable in its current form. The code for that screen (by Vovan and Progor) is self-contained and seperate, and I haven't touched it yet. The graphical issues result from using their code in BtS, and isn't the result of anything I did. I won't know what's wrong with it til I take a closer look, but I figured it wasn't broken enough to exclude.
As for the item ordering in the lists, sorry, I forgot about that. Basically what you're seeing is the order they're in in the XML files (e.g. UnitInfos.xml). I turned off alphabetical sorting in the code b/c I like it better this way, though admittedly I also re-arrange their order in the XML files some for my private full mod. If you want to turn alphabetical sorting back on, go into Assets/Python/Screens/ and un-comment (delete the ##) the line "##list.sort()" near the very bottom of CvPediaMain.py and CvBuilding.py.
The text keys are in the Assets/XML/Text/Sevopedia.txt file I included in the zip. I have to assume something went wrong on your end...
