Great additions. Can you provide some kind of confirmation or statement that you are not logging the data entered into bulk availability checks? This would put a lot of user's mind at ease, particularly those in the industry who may be using your tools regularly.
Looking forward to seeing DomainHole develop further. Excellent UI, UX and concepts.
I can officially state here that we do NOT store the domains entered into the Bulk Domain Check tool. If it would help ease users' minds... we can work on adding something to this effect to the End User License Agreement.
Also note that a video walkthrough of how to use the DomainHole tools will be posted at DomainSherpa.com this week - look for that.
