Clear and concise description of the problem

The feature is very simple, but as far as I am concerned also very important. Imagine, I had an already styled text like:

sdfsdf
    sdfsdf
    dfgdg
dfgdfg

If you would to copy the text above and try to add into anytype, it would remove the formatting. Simple tabs are not supported in anytype. However, they could be helpful.

Suggested solution

• allow tabs
• allow keeping original style of text
