Every time I'm working with Net Port tool is intolerable excruciating pain.
The reason is simple – If you click inside of it, you won't select it.
If you already had a selection and trying to select or drag multiple items – you'll loose all your selection and have to start over, sometimes more than 3 times!!!!!!!!
When you trying to click that thin border to select Net Port, sometimes you click at the tip and new wire starts... you have to SMASH Esc two (!) times to cancel it.
Compare this with a resistor (EU symbol) which you can easily click inside. As easy, as god damn expected!
This experience is the most frustrating with EasyEDA for me currently.
