Main-Button:

You can drag it to a new position with the middle mousebutton. it will remember this position on exit.
You can replace puppy.gif with another picture. The Button automatically will fit its size.

Personal Menue:

Add/remove/move entries with the Menue-editor available in the Main-Menue.

If you prefer the"old-style" way, here some tips how to use an Editor:
You can create a file like this, save it as ".myownmenuerc" in your personal folder:

<?xml version="1.0"?>

<RootMenu>
<Menu label="Personal Menue" icon="nothing.xpm">

<Program label="Edit Menue in Beaver" icon="beaver.xpm">beaver ~/.myownmenuerc</Program>
<Program label="Edit Menue in Adie" icon="beaver.xpm">adie ~/.myownmenuerc</Program>
<Separator/>
<Menu label="Utilities" icon="nothing.xpm">
<Program label="XFileExplorer" icon="dir_o.xpm">xfe</Program>
</Menu>
</Menu>
<Separator/>
</RootMenu>

Import KDE-Menue:

This is not implemented yet.
Feel free to write a script "importkde", that will convert the KDE-Menue to ~/.myownkdemenuerc ,it must have the same syntax as the personal menuefile.
