please go ahead Marvin, that’s what open source is for [mind that the script is not completely production ready, it doesn’t check whether at least 3 vertices are selected etc. so it might need some love.]
By the way, I only leaned from your tool collection just now and saw your GitHub: looks great but do you have a web page or somethting that describes the functionality available?
PS> for artists that are not too familiar with GitHub: Near the top right of the linked pages is a download button; click it to save the .py file, then (re)install the add-on in the usual manner. If you are familiar with GitHub it might be easier to clone the repo (Hint: I am always open to PRs )
