To add: The behavior is inconsistent also. For example, when content is copied from some PDFs only text is copied over, while for others Obsidian attempts to convert it to Markdown, sometimes very badly.
I see after I submitted this (sorry) that this apparently is a feature but it is not optional: Make optional - Turn on/off paste that converts HTML content to Markdown links
I have a degeneration in one of my fingers which makes adapting to this attempt to “help” painful.
Please provide a means to turn this off and paste exactly what was copied as plain text by default, with the option to use a smaller key chord (and ideally also a right-click paste option) to paste in the “helpful” converted text.
