OK, I have added checkbutton - if checked map is displayed.
New is also 'command' map, which may be any grass or shell command.
You can download via web:

Question for users: 
In current version, each monitor has its own region, which is independent of
grass (WIND) region. That causes two problems:
- monitor must be redisplayed before query (otherwise query lies)
- it is impossible continue in work from command line (for example
    display layers by d.dm and then query by d.what.*.pg)
Due to that problems I propose to remove that feature and synchronize 
d.m region with grass region. What do you think about?

Development of d.dm as it is written now, is discontinued from my side and
I want rewrite d.dm completely. It should be more similar to Gratia.
Screeen for those who were not in Trento:

I.e. gui: tree  + panel for options and internaly layers as objects.
