It would amazingly useful to:

a) Name tabs - Sometimes I'll have multiple log files open and they all have the same name, debug.log. It would be handy to be able to name the tab in these situations.

b) Sessions - I have to maintain a number of different environments each of which have several components that talk to each other. It would help to be able to save each of those logs to a session that I can open and close at any time. For instance, I choose 'Open Env A' and all 12 logs open up. 'Close Env A' will close them all, so then I can move on to 'Open Env B' and so on. I think LogExpert offers this.

Also, common features like the following seems to be missing:
- Close all
- Close all but this
- Pin
- Refresh - For when the OS hasn't yet registered the file modified event, this would "touch" the file in order to refresh the modified date so that changes will be detected.
