Recently I have been modifying my phi-2 shield to accommodate a 20X4 character display. I used sparkfun's 16X2 library when I started with my original design. Since there wasn't space for the bottom right screw hole, I went into the library and created a different package LCD-16X2-3-HOLES with only 3 screw holes and I saved the original as LCD-16X2-4-HOLES. I essentially did the same with 20X4 display. I drew a new package for the 20X4 display, derive from it a 3-HOLE version. Now I have 4 packages that should be linked to one LCD symbol in the LCD-HD44780 device. Here's the screen shot:



I'm confused on how to organize these four packages, with different technology or with different variants? I lean towards variants from just the meaning of the word. My purpose it to be able to right click on a schematic and turn a 16X2 display into 20X4 or switch between 3 mounting holes and 4 holes by selecting a different variant/technology. I hope I described it clearly enough  smiley-sweat smiley-sweat smiley-sweat

I'm not familiar with the "technology" option, but I've done similar things with variants - e.g. made my own pin header library so I can easily switch between SMT or PTH and vertical or horizontal headers without redrawing the schematic.

I'm trying to do the same. So you used variants. If someone can explain what technology is used for, that will be great.
