I like ubuntu/gnome's gedit for simple jobs when I'm not in the mood to wrestle vim.
Here's my pet peeves from a usability point of view
gedit 2.24.2 annoys me with:
1. Find and Replace across multiple documents should exist. Editplus does this with an 'all open documents' tickbox
2. If I open a filename which doesn't exist; don't show me an error. Create a new document, and when I save, create the file.
3. Give me a 'always reload when changed on disk' preference. I'm sick of clicking the buttons.
