Currently, it does not seem possible to delete tags or stars.
The root cause appears to be that htmx correctly sends hx-vals as query parameters when making a DELETE request, but the backend expects these values in the request body, causing the request to fail.
Please note that I have never worked with Go or htmx before, which is why I am opening an issue instead of submitting a PR.
Thanks!
Note you can use something like pdsls to delete them and the appview will listen to those deletes. but I should have this fixed later tonight
