When there are a lot of activities on the learning map, the activity page can look really messy. This makes it hard to see what's what and can be confusing with so many titles everywhere.
Removing the activity names helps cut down on the clutter, but it can also make things unclear. One good idea could be to add a bigger tooltip than the current one when the 'Show activity names' option is disabled.
When users hover over the activities, the names could pop up, which would make things clearer without making the page feel crowded. Thanks!
