A bigger problem was flipping components the graphics changed but the pin numbers didn't work right. Junction dots would sometimes go to weird places. Signal lines would jog around reference designators or values and the lines would 'fix' themselves when you move parts. The schematic entry did some weird things tying to be helpful. Overall I would probably rate symbol building as fair.
The grid snap doesn't work when moving symbol parts. The symbols were obviously built metric which creates rounding oddities when you use the US system. The library is pretty limited but there are some library items to use to build symbols which is a nice feature. There is a nice calculator feature for numerical inputs so you can do the math in place. I'm well past needing reading glasses so I found the icons too small. Right click menus are pretty well done and have most of what you would expect. It has some nice touches on the interface such as shortcut toolbar icons to switch between snap settings (2, 4, 8, etc.).
The performance is adequate although it does seem a little slow to load. The overall appearance if favorable and I like how the library is displayed. Since I'm no expert, there may be ways to tweak the behavior. This is not in depth just my impressions below are just from the schematic capture portion. I was interested in the sale price and downloaded the software to try it out.
