comment Legacy Text Interface (e.g. Telnet) to GUI
You aren't going to be able to generically update the UI and expect huge gains in learnability/ease of use. You need to study your users, generate designs and then test them. There are no shortcuts.

comment Are there any recent studies of the “Keyboard vs Mouse”-issue?
@JørnE.Angeltveit I feel like it is after having gone down this same road as you are going down. I am not familiar with NGOMSL but your work sounds interesting. I would like to learn more. Someone else deleted my answer; I took it to mean they felt it was completely unrelated. I was ok with that since as it stood it kind of was in relation to your question.

comment Are there any recent studies of the “Keyboard vs Mouse”-issue?
@JørnE.Angeltveit You are not going to find academic research to generically answer your question because there are too many variables to control experimentally. This is why KLM/GOMS exist. They are not theoretical models. If you give me an interface that supports both the keyboard and the mouse, using KLM I can tell you with a higher degree of statistical certainty which method is faster. However, that information will be of no value to anyone else unless dealing with an identical interface.

comment Are there any recent studies of the “Keyboard vs Mouse”-issue?
Based on the KLM and GOMS model, John's statement (If you don't know the keyboard command, it is usually faster to use the mouse) is absolutely correct. Mentally preparing takes ~ 1.35 seconds, moving hands to keyboard from mouse takes ~ .4 seconds, pointing with a mouse (excluding click) takes ~ 1.1 seconds, etc. You can review "The Psychology of Human Computer Interaction" by Stuart Card, Thomas Moran and Allen Newell or simply search for any research related to GOMS for more information.

revised Why left-align a website?
There is no supporting evidence that a centered design makes for an easier and better reading experience.

comment Floating submit/cancel buttons
Can you clarify what you mean when you say "users don't get an idea for the full scope of the form"?

comment Where can I find statistics on the use of mobile app features?
I can't imagine you are going to find academic research on "set as wallpaper" functionality.

comment UI Design / Flow - what should “Save” and “Cancel” do?
@PaulK Why don't you just run a test to find out what makes the most sense to your users?

comment UI Design / Flow - what should “Save” and “Cancel” do?
What you described might be true but consider this scenario: 1. User adds multiple records 2.User accidentally clicks the Cancel button If the entire form is a single transaction, the user just lost all the added rows as opposed to one.
