You can name your sketches to make it easier to find a sketch later when making edits. If a similar function was added to the used features in the timeline, it would be much easier to find a certain feature to edit. Something like this:
1. Add an optional description attribute for each feature in the timeline, e.g. "panel hole cut"
2. Hovering with mouse over the feature in the timeline displays the description
This would be a huge UI improvement since I often have problems finding the right one to edit, it takes some time but with a comment it would be very easy.
