How much "intuitive" user-friendliness do you demand from a new prog? in Sound, Stage, and Studio Posted March 1, 2014 When I write code with a user interface, making that interface simple, ergonomic and intuitive is usually 60% or more of the total effort. But I'm picky... I've had so much experience with badly constructed user interfaces that I make it a point to do it properly. Some of the programs I use at work are so non-linear it is necessary to write out lists of what to do, in what sequence, so you can do it again when you need to use it again a couple years later. Engineering programs (pro-level PCB layout programs, analog circuit simulators, RF and microwave simulators, CAD programs) are generally the worst offenders. Oddly enough, the lower-grade programs in these categories (for example, Multisim or Pspice analog circuit sims) generally have a much better usability, but often don't have the advanced capabilities I need.
