Comment:

 Replying to [ticket:2203 marisn]:
 > Some of autogenerated module dialog input options contain their default
 value. Current implementation has two downsides:
 >  * there is no way how to get back "default" value if it has been
 changed (a wish for a new feature)
 >  * once value has been changed, it gets added to the command parameters
 list (nice). The problem - if it's a number field (represented by a spiner
 control), there is no way how to remove it from the module parameter list
 (a bug)

 > Potential solution:
 > Autogenerate a button for each of input fields "reset to default". If
 default value is not specified, it should just clear the input field. If
 the default value is provided, it should just reset to default value. In
 both of cases it should remove parameter from module parameter list.

 In my opinion, the dialog would be too cluttered with all these buttons
 and we can't use for example context menu because we want to keep the
 system context menu. There could be one button to reset all fields but
 this probably doesn't make any sense.

 NOT provide cols or rows parameter. In current wxGUI form it is NOT
 possible to NOT use cols or rows parameter as soon as you have touched
 those input controls.

 There is already #1048, so let's keep discussion on this g.region problem
 there.
