Dear Po Lu, in the summer of 2024 I implemented a patch incorporating your suggestions. A couple of days ago I had a new look with the intention of finally submitting it. The patch corrects most of the issues you pointed out back then: nothing is touched in lisp/window.el, the variable is made terminal-local and it is implemented for androidterm as well. I don’t know how to indicate the :version for this terminal-local variable in the C code –or whether it’s possible–, please indicate how to do so (or simply edit the patch, as you prefer). A surprise emerged while rebasing to master: I discovered that since commit 2e8ef0910412aef8f9f1beba7c942473ad8602bb ("Protect against GCing of last_mouse_window”) all `last_mouse_window` of different terminals were merged into a single global variable. This is equivalent to my proposal in "Expose last window under pointer to Lisp” of 2023-08-22. This commit solves the original issue and, if you find it satisfactory, would allow to happily close this ticket. If you still think that implementing it as a terminal-local variable is necessary or preferable, I’m attaching the patch I described above. Note that I revert the changes introduced in 2e8ef09104 in my patch (please review attentively). Thank you for your patience and, as always, thank you for your work in Emacs. Kind regards, Adrián.
