Chanticrow,
This is exactly my current problem with Evernote. It used to be that they had this feature, but after the new UI redesign, a tab now indents everything. I complained about this months ago, and since the customer service is so horrible that I can't get a serious reply from anyone about it, it will probably be the reason I cancel my Evernote subscription after using it for years. This is probably the most basic thing for a typing application to have, and the only thing Level 5 moderators seem to latch on is that "Evernote is not a text editor", when it clearly functions as that.
Is there any actual fix to this issue yet? Is it in the pipeline to add the feature to change this? At this point, there's no point in spending money to use Evernote when something that any other platform offers for free can do this simple task.
Waiting to hear more on how this is being resolved.
