Criticals and a few other questions

Hi All,

Since SUMo is closing shop, I am looking for a replacement.

1)  I only want to update "Critical" updates.  Will Informer differentiate the type of update?  Can I sort them to the top as does SUMo?

2) will Informer do a table style list of updates (so more fit on the page) as does SUMo?

3) does Informer have a manual scan only mode?  (No automatic scans.)

Many thanks,
-T
