Hi, i recently tested the start8 trial version and i liked it a lot. Its a very good program. The only problem i exerimented was this: when i played videogames (principally league of legends) my pc gets very lagged (it gets slowed a lot) when i have this program open, and i didn't find a disable option, i closed the program with task manager and nothing happened. I think its a really good idea to put an option to disable/enable the program. I hope you read this 
Sorry for bad english, i'm chilean and my english is not perfected :/
