It would be a big time saver to preserve the style and formatting of a text layer, when copying and pasting it from one file to another file. Right now the paste operation loses all formatting and I have to re-format the text all over again.
I agree, the loss of formatting is a frustrating behaviour. My use case is copy/pasting text from an Email, Word or Excel file to create notes and annotations in my file (think bullet lists of requirements). This is different from pasting directly into a UI design where it is more logical to remove formatting.
I propose having a run-time option to paste as plain text or retain formatting.
