I've just downloaded Sublime Text 2, and like what I see, but have always used Notepad++, and it allows me to see space and tab characters. A space character is represented by a tiny dot, and a tab character represented by an arrow. When I highlight text in Sublime Text 2 I see these dots and arrows, but I want to see them all the time, not just when code is highlighted. How can I do this?
Also, I found that I can edit a theme by editing the theme's file. Is there any plan to be able to edit themes with a color picker in future versions?
