I think the one thing I do like in MM is the new MPRR; it's much easier to read as it uses sentence case and generally a little nicer layout. However, the PERMON team is using only EMAA output at my unit, so even that is wasted.
Maybe it would be nice if someone could tweak the EMAA output to not be a blinding POS THAT WON'T STOP YELLING AT ME!
(In an unrelated tangent, I thought messages were going to sentence format in 2012?!? May be just me, but I can never get used to the all caps writing; I find it jarring and a bit hard to follow where I am reading).
There is a lot of good info there but the interface is hard to navigate properly, and there is a lot of element specific items I just don't care about.
I guess it's nice if I want to double check someone's leave or something similar, but sometimes, that sort of function is 'sound powered', particularly as MM won't be up to date. The only real reason for me to use MM is to submit a leave pass as our CoC requires it, and even then that needs to get printed, signed, then manually entered into HRMS, so it's a bit of a waste of time. Also, it's down often enough that the old hand filled in CF98s are not uncommon.
