When I write python code I prefer to use whitespace instead of tabs. I like that I can specify the indentation level when I have the editor set to whitespace instead of tabs, however it doesn't respect this setting when using the backspace key. I've been hunting for a setting in the code style section but have not been able to find one that works like this. I'm coming from TextMate and it has a settings call soft tabs that does exactly this (it also shows these characters with hidden characters turned on instead of spaces.) Is this something that could be added to the IDE if it's not already available?
