[Feature Request] Detailed information view on the graph

[kateLint]

On the graph view, when pressing on specific point will popup view with details information of all data recorded at that point of time like: blood sugar level, sport activities etc.

This sounds to me as a very interesting enhancement.
Currently tapping on the graph shows a Toast message with the BG or a SMB at the particular location.
First of all it is almost impossible to see which dot on the graph you selected, so the BG Toast message is at this moment useless.
I would propose to either add a timestamp, or show a visual indicator on the graph which point you selected.
Increasing the time of the Toast message would be welcome also.
