Custom footers are in the development version (there are a number of issues with the development version yet, so you may want to hold off installing it, unless you just want to check out how the custom footers work.
The footer in TC{DF is essentially a single “cell,” thus, tables do well in the footer, as you may divide the footer into columns more easily.
To get an idea of how footers might look, check out my sandbox. There are a number of pieces under development and testing, so don;t expect everything to work on that test blog. ??
Footer options include vertical and horizontal positioning, margins, fonts, and of course, a box to enter whatever HTML you’d like.
I should probably start a thread (or group of them) for upcoming features, and make it/them sticky.
