I agree - and I have already outlined similar suggestions to the web author who is supposedly in the process of upgrading the spamgourmet pages.
[Our founders will please note: In deference to the philosophy of privacy which I find implicit in the existence of spamgourmet, I did not take it upon myself to send a long, unsolicited email to the upgrader. Instead, I first requested permission to submit, which was graciously extended.]
The suggestion most relevant to this thread was
[1]
Put all the controls on one page with the list of disposables: Send an email, change the exclusive sender, reset the message count, etc. This could be a fill-in form for everything at once, with one submit button; individual submits could be used for 'send from this address', although checkboxes which return all the masked reply addresses at one time to one end of the page would be great.
In light of the first post of this thread I would now amend my suggestion:
. . . and include 'select all' buttons for all appropriate items, such as hide/show disposables, reset message counts, etc.
