Yes, as long as I can link a piece of text to an existing Rem, and then that text is automatically added to the linked-to rem as an alias.
But it would also be nice if the one-way hyperlink suggested by @Tim_Webster is also implemented
A hyperlink could be considered a rem with a “one-way” reference. This would be a handy feature to add to RemNote anyway. For example, I might have an old term that I might like do link to the newer term (but I would not be interested in a bi-directional link, since I am just interested in the updated term). A “one-way” hyperlink could link to another rem or to an external URL.
Because at times you might need to link some text to an existing Rem, without it being an alias of that Rem, just the way you would link to a URL.
