Adding to my previously stated support for this feature with an additional example of why I’m interested, because the more I work within Obsidian the more potential I see for a feature like this.
Part of the reason I want this is that I rely on unlinked references to point out connections between notes and ideas that might not have occurred to me. So yes, I know that I could write “I want everything to be [[perfectionism|perfect]]” but the whole point is that I use Obsidian in part to see connections between things that I might otherwise miss. If I’m writing freefrom about goals, for example, and I just happen to be using the word ‘perfect’ over and over, it does me a service if my predefined alias points out that hey, you’re being a perfectionist again, maybe stop.
There are standard dictionaries, etc. for lemmatization, so perhaps those could be part of a solution? Obviously they should ideally be able to be toggled on and off, or modified according to individual needs.
Personally, I would like direct control over it. I want to be able to explicitly tell Obsidian that I want covid and coronavirus to link to the same page, or that perfectionism and perfectionist and perfect should all link to the same page.
