I noticed that when in "single-edit" mode, if i click multiple tasks, all the tasks that i click get highlighted. Visually I think this is a bit confusing.

Please note that functionally only the most recently clicked tasks is available for editing (which is the correct behavior). Its just that the I find the multiple highlighted tasks (in single-edit mode) visually distracting.

My suggestion is to highlight only one task (the most recently clicked) when in single-edit mode, thus making the User interface more intuitive and clear.
I hope you consider this suggestion.
