Hello Gary,
Thank you for your proposals. Here are a couple of questions to clear out:
1. What are you going to write in "group" field ? Just free text ? Provide please some samples what would you write there
2. Sorting is possible in Settings...
3. But common combobox control on the toolbar is very limited, all we can show there are text values. But, instead of using this drop-down, we could shown own "Pick connection" dialog, that will look like this drop down. In this case we could implement there any functionality: sorting, searching, etc...
what do you think ?
