There’s no timeline or roadmap at this stage, but it’s definitely 46+ material and likely to take multiple cycles. There are individual parts of this that could be worked on independently ahead of the more contingent pieces, for example tiling groups or new window metadata. Help in any of these areas would be appreciated.
When can we (if ever) expect that auto-tiling thingy?
