Topic: Interface tweak / Two-rows toolbar layout
The screens on which I use Siren are usually quite small (netbook size, 1024x600). On version 2.x I could rearrange the toolbars in a more compact layout to save space, but no longer in the 3.x tree, probably due to its cross-platform nature and the use of wxWidgets.
However, since the current toolbar layout leaves a lot of empty space in the first row, and the expressions are seldom very long*, I think it might be worthwhile moving the expression box in the first row on the right of the buttons.
Perhaps this could be decided by the user with a "Use compact toolbar layout" checkbox in the Display preferences (or maybe in General, since it would probably entail an application restart just like changing language).
*and in the remote case they are, one can always scroll horizontally in the expression box...
