Animation durations

The issue here is not only about the length of animation but the STYLE of 
animation. This is of course my own personal small tests on friends/family 
(they are hardly anywhere near definitive or even scientific) but the most 
hated bit isn't the speed but things like the "lagging animation".

You know the one where an exaggerated "click box" hoovers after the mouse 
pointer in system tray and on the netbook layouts "Search & Launch"? You can 
still click - it doesn't say anything, it doesn't give the user any 
information - its simply decoration. But every single one got annoyed and 
ignored clicking until it became "aligned" with the mouse pointer.

Speed in sliding windows or for that matter things like the launcher can be 
annoying since again its only decorative. (personally I turn off all 
animations but thats just me)

Plus there are two issues at play here: 
1) Should the speed be configured by the user
2) How the hell do you configure the speed?

I'd think that the second demands a fresh look at system settings and how they 
are laid out and how to make them more easily navigated, interacted with and 

The first one I'd say: set the speed and style of animation (lets just set a 
good speed) - just make it editable at most base level with three speeds 
described as words. (like it is now) Then if possible let the style be 
predefined or handled by the effects tab?

Since we don't have time for making a thorough research into it and barring 
whether we can find any I'd suggest let us the devs test it at home and 
publish suggestions here and then assume that whatever sticks is the correct 

tl;dr If configurability becomes even a slight issue, ignore it and we set the 
"Carthage should be destroyed" addendum: We need to look at the system
