Important topic! Totally agree that context switching has a heavier cost than most people realize. That's also why so many product/dev teams are optimizing for tools that improve dev productivity and collaboration.

I asked representatives from 200 dev teams around the world how well their developers & non developers communicate & collaborate with each other while building products. Here's what I learned along the way.
You might want to check out what the team at Livecycle is working on. They just rolled out their SDK to add visual commenting/collaboration on top of your existing preview environment - https://www.sdk.livecycle.io/signup
Check out Livecycle (https://livecycle.io/). I'm part of the team there and it sounds like it could be the tool you're looking for, since our aim is to make the review process more organized, clear and collaborative for front-end teams.
The platform lets teams collaborate on top of PR preview environments where all relevant stakeholders can comment with text, screenshots, video captures, and by easily editing HTML/CSS elements, as you mentioned you wanted to do.
All review comments are organized in the Livecycle playground (with relevant notifications for playground collaborators) and also synced back to Git where developers can see them in full context.
So using Livecycle, your team will be able to clearly collect UI/UX feedback from everyone, and avoid unnecessary tickets and emails. The whole process becomes transparent and collaborative (for both technical and non-technical stakeholders).
It takes just a few minutes to set up, and at no cost. We're available and happy to help and answer any questions and also to tell you about our upcoming rollout of an SDK...
