Redirecting to a destination with state

I'm looking at the plugin and hit what seems to be the perennial issue.

if you setup a redirect from `/a` to `/b` , after creation you can add a querystring and hash to the url and it will be appended to the redirect. Great so far. (`/a?tab=2#myheading` redirects to `/b?tab=2#myheading`)

However if you say want to redirect to a destination containing a hardcoded querystring/hash then that's not possible as it gets stripped from the redirect on save. (from `/a` to `/b?tab=2#myheading`.

The use case is publishing a short url in print and it loading say a page with certain state. Another usecase is a redirect to a javascript app that handles internal state.

I might be able to have time to look at this. Is it desired, or have people solved this another way?

Start by reproducing the redirect setup described in the issue: save a destination containing a query string and hash, then inspect the resulting redirect. Trace the plugin's destination-save and redirect-handling paths, and confirm completion when hardcoded destination state is preserved without breaking appended query strings or hashes.
