I have been trying StartAllBack since upgrading to 24H2. StartAllBack feels like a very polished replication of older Windows, but now I run into this issue, if I have too many windows open and I hover over them in the taskbar, the window list hover span two columns instead of staying in 1 column with a limit of items shown, with vertical scrolling to access all of the items.
Moreover, the window titles are not truncated at all, and the 2 fixed-width column design makes it worse, 1 column with an extra long title makes the second column unnecessary long also, making the whole hover fill up the entire screen.
