OS X APPS
Mail Satellite
Mail Satellite lets you display unread emails from your menu bar. Quickly view an email to reveal, reply, or delete directly without opening Mail application.

popCalendar
popCalendar is a tiny calendar that fits in your menu bar giving you a faster access to your timetable. A presentation per month lets you find the day or the date you need while a click on a day lets you see all of the events of it. All of that without having to launch iCal!

iRamDisk
iRamDisk uses a part of your RAM to create a new volume shown as an ordinary drive that can be mounted and used independently in your Finder. Since the access time to these datas is way more faster than usual (it can reach over 10 times of the normal speed for some configuration), it lets you do some things you would not be able to realize with a classic hard drive (along with relieving your internal one) such as getting a writing speed amazingly fast or moving the temporary files of some apps (Safari, Xcode,...) over it when you want to optimize their own access time along with minimizing the impact of these files on your SSD.

However, do not forget that your computer does not have as much of RAM as your disk space and that you will lose the data placed on the new volume when you restart it. So, be careful when using it!

SpotFiles
Find files with advanced criteria and without Spotlight engine.
Create snapshot of tree directory to allow comparison with previous state.
