This is the first time I've heard of your program. I've just taken a quick
look at it & I must say I'm impressed: at last there's a GUI builder that
does things right! Great work!

I have a few suggestions to improve the usability:

* When the user clicks on a row/column/constraint in the layout builder, the
appropriate properties tab should be selected automatically. For example, if
I click on a column header I would like the column tab to be selected for me.

* Have some toggle buttons on the toolbar for switching between the layout
builder and presentation builder views.

* Consider having the builder toolbars running down the left hand edge of
the window. At the moment the buttons are a little too far away from the
work area and a lot of mouse movement back and forwards between the two is
required.

* At the moment you have to be familiar with the JGoodies constraint syntax
for rows and columns; it would be even better if you didn't have to be. For
example, if you could choose the constraints from a number of drop-downs
(one for alignment, one for size, one for resizing behaviour), that would be
quite helpful.

* Same comment as above applies to borders, too.

* Some of the menu items are a little confusing. I initially thought "Focus
Editor" would bring up a window/view where I could edit the focus order of
the components in the panel (which would be a nice thing to have, BTW).
Changing the text to something like "Move focus to Editor" would make it
clearer.

* Labels should be automatically added to the presentation builder too.

* It should be possible to add a scroll pane to the panel. If it is possible
already, I couldn't figure out how.

That's all I can think of so far. This is a great program already & I hope
that helps make it even better. Thanks for developing it!
