I hesitate between classical editors (like MS Office, Open Office) and online editors which provide more accessibility.
I would say that I'm looking a polyvalent text editor to write my thesis. I'm student in Biology thus I would need an editor which offers me a lot of good practical features like autosave, support for summary, pagination, bibliography, but also provides in easy way to layout presentation, add pictures, equations, graph, ...
I will define the comfort by the ergonomy of application. I don't want to use a cockpit fly. Only few buttons which make sense.
By knowing that I'm going to spent a lot of time behind my screen to write my thesis, I would like to know which features, writers like to have in their text editor and why? Regardless of their activity field.
