improvement sugestion: inactive wigets on tab

Hi, i love your plugin better widgets, i hope it will do into the main code someday soon.

for now i have some improvement suggestions:

first: instead of putting inactive widgets on the bottom of the sidebars, for usability and consistency i would divide the right pannel with two tabs, one for new widgwts, and another one for inactive ones.
this is also a way to safe widget configuration.
think of putting a button inside the widget box to deactivate the widget

seccondly: and this is a more critical idea.. sidebars evolved a lot since introduced. today putting the widget configuration under themes menu is not coherent. for a consisten menu it should have its own main menu, for example “sidebars”
