Comment 517 for bug 532633

If this can be considered as a valid data, I for myself _strongly_ disliked the change at first, but gave it a try (that's what the development version is for). After few days I get pretty used to it, and now I can't imagine having the buttons on the right (pun, pun) side. The key benefits for me are:

* less mouse movement indeed
* better orientation - all control elements AND the title are nicely grouped together
* much cleaner look (that's totally the matter of personal taste)

Nevertheless, I will keep the old button layout on my mom's laptop in the future, unless she ask me to do otherwise (I'm a good son, You know).
