DroidEdit is a text/source editor that supports Syntax highlighting for C, C++, C#, Java, HTML, CSS, Javascript, Python, Ruby, Lua, LaTeX, SQL, and much more. You can download/upload source directly to and from your DBox. You also have the ability to run external SSH commands. Code, compile, and run your programs on the go!
I don't really like taking my laptop out on the bus/trolley, so this is an easy alternative. In my opinion, the app is very sleek and a lot more functional than all of the other source editor apps that will work your phone.
AirDroid allows you to connect your phone to your computer wirelessly. The desktop UI is quite inventive and easy to use, and yes, it does include the standard file browser. You can connect to your home computer through your home wireless network, or you can use your mobile data internet and connect to any computer around the world (great for troubleshooting).
Personally, I like being able transfer files without having to properly eject my phone from the computer.
Flash Image GUI eliminates the hassle of installing a custom kernel or recovery ROM like Clockwork mod. All you have you do is drag over the kernel or recovery image to your SD card, select it through the app, and it does the rest for you.
A fucking life saver! When I first found it, I thought for sure it wouldn't support my phone, but I was dead wrong.
