It can be hard to navigate a container’s terminal output in Docker Desktop - often there’s numerous lines. The filter option works well, but it would be great if, when filtering, non-matching lines disappeared, or at least were greyed out, so matches were easier to spot.
Creating a feature request on the forum could be a good way to discuss it with the community, but I recommend you to open a feature request on GitHub in the Docker roadmap, since the people who could make a decision and implement it are usually not here on the community forum.
