Its annoying that when I change the grid width and then continue working, the value is not changed -- I need to click in the other grid field for the value to be recognised. Also I think it would be better if the grid value were global and not stored with each layout (perhaps this could be set in preferences).
Also it would be good if all shortcuts and buttons were able to be changed in preferences. I use F4 for running the project and would like to set the 'play' button to run the project and not the layout.
