The changes in the daily are pretty much it for the 12 release, the primary one being the ability to access both the pattern's and the base geometry's UV maps. Direction indicator should be handy too.
The caps may be useful, but these only work on holes created by the Crop Box, so if for example your source mesh already has a hole at the edge of the crop box, this will not be capped by this functionality (you have to cap the source geometry), nor will holes created by having partial tiling such as 1.2 rather than 1, just to help guide anyone doing testing on there.
The plans and answers to things on the list you posted will have to wait until 12 is out and we look ahead to future plans, as we're entering into the final run up to release in just over a month, making it all hands on deck focused on the 12 stuff only. We do have all these ideas tucked away to look over when we get there, though!
