Redundant animation and redundant windows
When you minimize 10 explorers and restore 1 of them, 10 of them are restored. You can do nothing but watch the long animation. Meanwhile, if you press Alt+Tab, there are some redundant windows created by WindowTabs. So I'm afraid the pattern of the program should be reconsidered.
Fixed in version 2013.1.23 – use the WindowTabs task switcher to avoid redundant windows (look in “Behaviors” section of settings). Animation is much quicker now
I have a fix for the animation will be included in next release (I'll close this issue when its available). Regarding the extra window in ALT+TAB, you can use the custom taskswitcher with windowtabs (CTRL PAGEUP). I will be adding a better task switcher to replace the ALT+TAB in a future release
