Just an easy script that moves Gmail attachments from bottom to the top of your email.
*added some visual updates (padding, rounded corners and background color), that can be easily turned off, by just deleting the "GM_addStyle" lines.
20.02.2015: a bit edited code, faster and works with every gmail layout not.
23.02.2015: updated code, fixed bug, when attachment kept multiplying. Now code activates when page fully loaded after every move (instead of every 5sec.)
16.04.2016: updated code, basic mutationobserver instead of non-stopping DOM listener
