So I got myself a Raspberry Pi 2 this month. But due to some display connectivity issues (lack of HDMI monitor, USB keyboard,etc) on my part, I was unable to use it.
Finally now though, I have got it up and running. But there are a few customizations (and fixes) that I had to do before it became usable for me.
1. The terminal hotkey
My number one problem was that there was no terminal hotkey (that launched in the same x session). I sorely missed that, needing to click on the taskbar icon and then shifting onto the keyboard to type the update and install commands.
Adding the shortcut is no biggie. Do the following:
sudo leafpad ~/.config/openbox/lxde-pi-rc.xml
Find the tag and paste this line just before it:
