Yeah, well, there are issue that need to be resolved. I am doing SteemWatch in my spare time, so I don't have too much time for fixing issues and adding new things. Right now it is having some scalability issues that I am going to address next before doing anything else.
No, there are no notifications for reblogs yet. Created https://github.com/tchap/steemwatch/issues/42 in case I have time to implement it at one point in the future.
