It would be convenient to have these options with following example logic:

(Bug || Feature request || Support request) && (Open || Closed)

That seems like super specific feature. I think you're misusing the Roadmap tab if you're searching for a list of open items to work on there.

Moreover, with just 1 click you can get a list of open items ("1 open" hyperlink below the green progress bar on your screenshot) from Roadmap if you need that.

1. Issues tab (add a target version folder and hit apply)
2. Saved query (pre-save a query and then only click on a link)
3. Agile plugin's Version Plannig screen
   to name a few
4. Gantt tab (If you really only need a 'quick glance' at open items go to Gantt tab and scroll to the target version of your choice. Status > Open is default there)

I would more likely go the other road and would remove the list of issues completely from this view. It's redundant to the versions details page and makes it hard to get a quick overview on the state of all versions. As Dominik wrote, details to open and closed issues are just one click away.

What I want to do is to see all open issues of all versions on the roadmap page at a glance. The page is really convenient to understand the current state of the project.

I don't think that placing "open" and "closed" checkbox there to filter issues is odd because there are already checkboxes for trackers.

For that I prefer the issues list view a lot more as it is more flexible and informative than the roadmap. I have more columns with the possibility to reorder the lists and see overdue issues at a glance.

I see the roadmap more like a dashboard where I can look after the overall health of my projects. The roadmap should signal to me, in an easy to visualize way, if my intervention is needed on a specific place.

IMHO, further checkboxes would make the UI more complex and filtering issues shouldn't be in the scope of the roadmap module. We have a module which is superior for that purpose. I would rather prefer to have a link like 'All version issues as sorted list' which I think has a higher benefit for the user.
