5 sourcesMattermost PM here, I agree that this is not a good experience, thank you for sharing @jetru.
There is development in progress to let you jump directly to new messages when you land on the oldest unread message in a channel. This lets you get directly to the latest message.
I'm not entirely sure if this is the same use case you have, but if you're open to testing the new development and share feedback, we'd love to hear!

In Story of Mattermost: Open-Sourced Competitor to SlackAsk HN: What open-source projects are you looking at?
I have found reading code is a good way for me to improve my skills. I am looking at Mattermost[1] and Spectrum[2] to improve my React.js.
What open-source projects are you currently looking at?

11 points · Open discussionAsk HN: Join React.js Open Source Study Group?
I am an experienced back-end developer and have been learning React. I have done a couple of introductory courses on Udemy and feel comfortable with the basics.
I want to create a study group that looks at a sizeable open source React project in order to learn advanced React. The current project I am looking at is Mattermost [1], which is an open source Slack alternative used by Uber.
The idea is to learn from the architecture of a large project and try to contribute to the project. Mattermost recently raised $50M [2] so might be willing to allocate a developer to help teach us if we have a reasonable size group.
Open to other project suggestions as well.
