Writing the Thesis is a big deal, however right tools makes the experience a little bit easier..
I’m using Gedit on steroids, which is quite easy to achieve.
Just get the LaTeX plugin, and the to get all your files up and running in no time, try to gedit manager plugin.
Then use Classic thesis.
One more tip about screenshoots. Long story short, your video resolution will be always a bit short for the rendering in printing, so if you can’t use svg (made with Inkscape) or pdf or anything that is not a vectorial format you have to rescale (up) the png picture, which is tricky.. ’cause you’re trying to make more info from less.
However if you take the picture at top resolution you can use gimp scale tool to make a decent work.
To do that open the image (png, jpeg or what you’ve got) with gimp and then increase the resolution to 300×300 dpi and then change the canvas to a decent dimensions and scale it up.
This should make you rolling. Hopefully 🙂
