Feature Request: Reloading an environment re-opens all the map files that were open before the load

[MMMiracles]

Problem to be solved

If you're actively working on map(s) that are using custom code that is being actively developed, you need to reload the environment to get an updated tree list. The problem is this doesn't remember any of the previously open map files before you did this and you need to keep re-opening them as you make code changes.

Sugest a solution

If you're loading the same dme file while maps are currently open, attempt to re-open these (ideally in the same order as you had them) so its easier to jump straight back into editing.

More of a QoL feature than anything, would be nice to have when you're actively developing a feature that has multiple custom objects.
