 The use of the layer's 'Query' function is difficult when used frequently
 : if you make a query than choose to modify it you have to open the query
 window, erase the existing query, close the window, reopen the window,
 type the new query then close the window again.

 It requires 6 steps to update the query if the new parameter concerns data
 previously left out, if the user doesn't follow them the query tool will
 notify him that there is no data corresponding to his request due to the
 limited subset being actually used.

 A solution would be to offer an 'Apply' button which would applied the
 query on the source data, discarding any previous queried subset, without
 leaving the query window.
