You can switch off the working tree display in the Log graph in the Preferences, Low-level Properties, log.workingTreeState.

No, it's not planned for 18.2.

Will become a valid option (not experimental) in 19.1 

Please contact smartgit@syntevo.com and include a detailed description of which steps you are taking and where results become unexpected.

It works with both gitlab.com and self-hosted instances. Do you have configured your GitLab server in the Preferences, section Hosting Providers?

Thanks, Robert. This will be fixed for 18.2 preview 10.

When having GitHub Hosting Provider configured, in the Log, Details view, there is an additional "Open" link. Isn't that sufficient? If not, please explain why and give more details on where exactly you expect to see a "Copy GitHub URL" action.

Basically, what you are suggesting requires a Log (most likely of the entire repository) for every refresh. That will be too expensive.

Can you please give more details on where you would expect to see this functionality? I guess the Log Files' view would be the appropriate place?
