@maclean: my post had been done from the view of a Vue-user. Being this, I like the way how Studio handles the files (size), I like the easy way how I can alter textures in Studio (attributes), knowing the gyro I can't say how I ever got along with the dials. There is more to Studio that makes it first choice (you've mentioned some of them - having a fast and friendly feetback is just one of them). De-installing P4 and P5 left me in no way more "poor". It resulted in gaining speed and HDD room. The post had been done not to advise anybody to do or don't anything, just a reminder.
