Idea: reverse rows with columns

[PaulRBerg]

Rationale:

1. Wallet names are shorter than features, hence more features will fit in the initial page render (assuming that column headers can be split on multiple lines). It wasn't immediately obvious that I had to scroll right to see all wallets.
2. This repo would become more neutral this way, as all wallets would show up initially instead of only the first 8.

Optionally, for this repo to become even more neutral, wallets could be ordered alphabetically.
