Note that this should not be used as a demo version of Xee³. Xee³ contains many large changes from Xee 2.2, and they can not be directly compared. Also note that development has ended on the 2.x branch of Xee, so no new features will be added, nor will bugs be fixed. However, the source code is available, if you want to make changes yourself. Xee 2.2 should run on both Intel and PowerPC machines, on Mac OS X versions as far back as 10.4.

Homebrew - The missing package manager for OS X: http://brew.sh/
No, that's MacPorts.

Since Bean is no longer being developed, I'd recommend replacing it with Growly Write, which is excellent, small, and very actively supported by its developer Chris Mason, long ago project head for Microsoft Word 5 ("back when Word was fun," as he says). http://growlybird.com/write/index.html

Also, nothing wrong with FileZilla, but why a separate app installed when you can use the excellent FireFTP add-on for Firefox? http://fireftp.net/

I was impressed by what this program can do, definitely worth giving it a look to compare it to CLeanMyMac and others...
