I just found a bug related to diodes.
When I place a diode, it says first "click on cathode hole" then click on "anode hole", but it places the bar to indicate the cathode at the wrong end.
I just didn't noticed when I entered the diodes today, but tonight while I was checking my circuit a last time, I realised that all the diodes were the wrong way.
The funny thing is that I only noticed one diode at first, and and it's only when I tried to replace it the correct way a few times without success that I found out about the problem, and noticed that the other diodes were also all wrong...
Also, now that I want to replace some diodes by LEDs, I realise that a LED component would be very useful. In fact, I really need it because I use LEDs on pcbs quite often.
Added: Ok, I think there is a bug with the "replace" function with the jumpers. It just adds a new jumper without erasing the original one.
