Hi Ed,
#1) confirmed, will debug this
#2) same category of problem, will run all tests under View Mode to make sure everything is fine
#3) we are aware of this problem, but we consider there would be too much effort to put at it than it would benefit afterwards. When you open a page, the tab is named after the page you are opening, and it isn't updated afterwards.
There would be a lot of scenarios to consider to make this perfect. The page name can change for many reaons: navigate to another page, edit page name from page settings, etc. etc. We would have to be able to intercept all possible page name changes, which represent a lot of work. Also, we ensure that only one window is opened for a particular page, so that if you click on that page again in the menu, it reuses the same window. When navigating to another page, if that page is already opened, we would have another class of problems.
If you think this is critical, please tell us. But we would rather spend some time on implementing new cool features, such as code snippets and keyboard shortcuts, than spend much time to work this issue out.
Thanks for reporting these problems Ed.
