There should be a user-selectable option to auto-remove "dead" tabs.
In the current implementation, there is a problem.
As a result, the deleted document will be displayed from cache.
With dozens of open tabs, this may be confusing and cause inefficient workflows for users.
With the auto-remove option enabled, tabs should automatically disappear, when users delete referenced documents.
As a bonus, there may be even a periodic cleanup task, which checks on "dead" tabs (both documents and databases).
