Is your feature request related to a problem?

Describe the solution you'd like

First of all, thank you for developing Gaphor, which is very simple and practical. During my development process, Gaphor has become the main modeling tool. The alignment function in the Tools menu is the most frequently used when drawing. Can you place the alignment toolbar in the interface, such as in the lower right corner or allow users to customize placement?

Describe alternatives you've considered

After selecting multiple objects with the mouse, right-click to display the alignment menu.
