show all issues EXCEPT the ones with tag "no code attached yet".

This particular is quite simple. Just filter on the status (not label) Pending: http://issues.joomla.org/tracker/joomla-cms/?sort=issue&status=3

Thats are all Pull requests that not set RTC, NRW, Information Required ;)

Other way arround is: https://github.com/joomla/joomla-cms/pulls as this shows all Pull Requests.

I'm not sure if we can implement this in a easy way ;) But that is my no coder position. Maybe someone has an Idea to implement it.

Either way, it isn't too terrible. It's basically turning things into a multi-select, making sure the values get read out of the request correctly, and changing the WHERE clauses of the query from WHERE tag = 3 to WHERE tag IN (3).

We have a "special" table field has_code to differentiate issues from PR, so we might just add a new filter to have a display the GitHub way using issues or pulls (or both).
We could have a multi select for labels, as @mbabker said.
Or we might just implement both

@javigomez we have #703 now. Is it enough?

For me it works with the type filter although this only works for the difference between issues/PRs and not for the rest of the labels. This already helps me a lot. Thanks.

Nice :) But multiselect would be greater for labels, yeah? :)

A multiselect would be more flexible, just don't know how often it will be used. Perhaps leave it as-is and wait to see if more requests come in for it.
