Explain what a "merge train" is
This is an actionable insight from the UX Department: MRs experience async critique research (insight).
What
In the merge request widget, the term “merge train” is used without any explanation.
Why
Many people are familiar with “merge” but “merge train” is something different. Even people that are familiar with Git might not understand what a “merge train” is.
Making the UI more understandable to more people makes it easier for them to adopt the product, not only because they feel knowledgeable enough to use it but also because it makes the product friendlier and more useful.
How
Explain what a merge train is, especially when users are faced with the choice of using a merge train (see screenshots above). One option is to add a question mark icon with a tooltip/popover that explains it using simple language and also links to documentation for more information.
