Feature Request: uncheck all / toggle all

[aslmx]

Hey,

First thanks for this nice little helper app! It has helped me already so many times.

I know it's been a while since the last update. But what really bothers me alot is that Bulkshare will automatically select all entries when i launch it. However, most of the time I want only to share one or maybe two links from the long list of "todo" items I have in the list....
Then it is really an effort to uncheck all the ones I want to work on later...

Can we have a "toggle all" or "uncheck all"?

And if it is not too much to ask: a setting that controls this behaviour, so that people who like the way it is can have it that way and people who prefer the way i propose can use it this way.
It could be called "Check all items on App start" or similar.

Thanks!
