[Feature Request] Duplicate tab handling

[sageacy]

I purchased Pro, thank you for the great extension!

There are several chrome extensions that provide duplicate tab handling. Many of these are open source to get a sense of how they work.

Although are existing extensions, I believe duplicate tab handling functionality would be much more effective in the context of Link Map, and likely could be a Pro feature.

Within the context of Link Map duplicate tab handling could offer the following features:

• configured duplicate tab handling (ignore, warn, open existing)
• flag duplicate tabs in the link map outline view
• filtered view that will show all duplicate tabs
