Non-standard window ordering?

Most Recently Used (MRU) ordering criticized: http://www.azarask.in/blog/post/solving-the-alt-tab-problem/

"At the same time as the switcher program is trying to learn the user's common patterns, the user is also trying to learn how the switcher works."
Someone "suggest having new alternative to Alt-Tab that has static positions (reorderable for the power user.)"

Should alttab implement some crafty ordering of windows as an option?

Anecdata point: I found Alttab specifically seeking a tool with MRU switching. My setup of i3 and Rofi provides good, usable ways of switching to a particular window, especially on the current workspace. But it lacks any mechanism for tracking MRU order, and that's what I would find useful.

The reason why I am using alttab is MRU. I like how I can easily switch to one of the last used windows (most often just the last one, though). I also use i3 and rofi for switching to specific windows via name or position.
