Hi @anon34495098 and thanks for taking the time to share your feedback with us!
We already have some existing threads for the topics you’re referring to and I’ve also split your feedback about Slack. Feel free to add you vote and comments to them 
- [Slack integration] Ability to poll Timeline view data into a Slack channel
- Filter Timeline view by Section
In regards to your question about colors in Timeline, I suggest you checking this section of our guide article for Timeline.
With that said, please try to keep one feedback only per thread, so other members interested in one particular feedback can vote for this particular feedback as opposed to voting for all by default. It’s also a lot easier for our Product team to collect feedback from the Forum, and for us Community Manager to follow-up on!
Feel free to make any adjustments you need to, and of course, if there is anything else I can help with, please let me know!
Have a great Friday!
