In KiCad V5.1.x all open pins have a small circle in the schematic (upper left), while in KiCad-nithtly V6.0.0-rc1 (Lower Right) these are not shown.
Is this intentional or a bug?
Could this be a user setting?
I much prefer these circles, as an indication that there is still work to be done on the schematic. Especially as long as Eeschema relies on the matching of endpoints between wires and pins. Without these circles, there is no indication when for example a “No Connect Flag” is placed close to a pin (but not connected).
The strange thing about the bug report example: If the wire in question is not connected, why do we see a junction dot? This question is probably moot if the issue is being (or has been) fixed. But to me it seems that the dot is more than just hiding something; it is lying.
