While I like the idea of disabling the sorting cloud, I would very much like to have the option to put stars on a topic for easy reference.
What I would like to see is instead of just a box to click, to have a drop down with the options: [Advanced Sorting - Cloud], [Basic Sorting - Stars], [No Sorting].

I am also wondering what this option section acts like if you haven't unlocked the cloud? Would be good for it to say [Option locked - Unlock in Credit Shop]

I totally agree with Kyphis.

I used stars frequently, while the cloud itself - not at all.
PMs open much faster without the cloud cause of the additional flash animation (that's only my guess ) but stars ain't a problem and are quite useful

Bump.

I want my stars back, without the annoying sorting cloud T_T
