We are building a way to install/update themes a bit easier and done entirely from the ACP. When upgrading and installing, we were wondering what you would prefer: enter FTP info to download or make your js/styles folders writable.
If you make your JS/Styles folder writable you don't have to do anything ever again. But if you are going to enter FTP info, we wouldn't store that info so you'd have to enter it every time.
Let us know!
