Active Tags like multiple selecting

The current solution for display multiple selections(the entries are simply entered into the textfield, separated with a comma), isn't the best. Its difficult to delete entries and the textfield is only able to show a certain amount of entries, since you can't scroll.
Therefore a new system will be introduced to display multiple selections. It will be similar to the one in the active tags, but I haven't thought out all details.
Basically entered items will be show above the textfield as small boxes and will be deleted through an "X"-Icon. I think that, this could solve a lot of problems and will surely be more user friendly.
I can't say, when this feature will be available, since other things have priority first, but I think it will be in the first major release.
