Which 'old' button?  I think that the button is the same since it was
added in 2.11.

It would occupy one more line, debugging bar is usually hidden. I
could remove the text from the button to make it smaller, but I wanted
to express di difference between closing the widget and closing the

It is hard to decide, maybe optional?

'New mapset' is rarely used, and for an existing location it is much
easier to create new mapset from browser. 'Open mapset' is something
which I would like to remove completely, once user get used to opening
mapsets from the browser. It is the last old style open dialog (in <
2.10 it was used also for rasters/vectors).

When I was adding the 'Close button', I considered also other places,
like toolbar or menu above the tabs widget, but I think that an
application should not have preferably more menus/toolbars than the
main application-wide.

One (I if you like) can add g.mapsets with the s-flag as a module (I tested "g.mapsets -s" in the QGIS-GRASS-plugin and it starts the GRASS dialogue successfully), but it is probably better to have this option a bit more prominent (as it might come in handy with the new multiple map input option)?

My approach, since the plugin was introduced, is that we do not add a
GRASS modules since we have a decent, dedicated GUI in QGIS. That is
why I never liked things like nviz in QGIS. This approach was
partially overcome by reality and various hacks (IMO) requested by
users. In this case, I would really oppose to open GRASS GUI from

Maybe you manage to write a wrapper GRASS script for g.mapsets in
Python which fills 'mapset' options with existing mapsets and sets
'answer' to the mapsets in search path?
