Change color settings and various memorizations(file, caret position,...)

Hello Dev
By installing the EditorSettings plugin, I managed to change some display settings. However, I am unable to:
1/ Set a background color for the active line.
2/ Change the general background color of the window where a file is displayed.
Also, as I see that BowPad has a pretty powerful setting, I'd like to ask you ifis it possible that:
BowPad remembers open files when you quit? In order to reopen the files you have been working on.
BowPad remembers the position of the caret and any text selections in each file?
I hope I'm not asking too much...
