Those amp hour names? They certainly make it hard to find stuff.
In regards to Kicad, I tend to have more issues with Altium reader than Kicad. I don't have normal Altium.
The other day I tried to open a schematic in Altium reader by double clicking on it.
Altuim duly opened up, it told me useful things like I was working in offline mode and that I should register, gave me a list of other schematics and designs that I may want to look at, but no sign of the schematic I actually wanted to see.
It turned out the .sch file was probably an Eagle schematic not Altium, but no message to the effect that file is wrong format and the file didn't open.
Bad UI is not restricted to open source.
