I dont completely understand the relevance of this button which is shown when clicking the 'three dots' on an activity.
The option to add a vehicle from the fleet is already available for every activity and both methods give the same results.
Besides, the naming of this function also feels odd. Im not adding a activity to the fleet, but a vehicle from the fleet to an activity.
I would advice to get rid of the 'add to fleet' function as its double and the 'fleet +' option in the activity on calendar view is more intuitive and easy to use.
Lastly, it doesnt show the expansion/dropdown arrow '>' but when hovering it still randomly shown the entire fleet to select from. So this function has a bug as well.'
