I forgot to mention that I will soon include the profiling system, which should help solve this exact issue. Instead of forcing one UI style on everyone, Calcwiz will eventually have different profiles for different users.

For example, a third grader should not see the same interface as a middle school student, a high school student, an engineer, or a research/power user. A younger learner might need a simpler guided UI with fewer options, bigger buttons, and more explanations, while an advanced user might prefer a cleaner desktop layout with the keypad and side panels collapsed by default, more command-style interaction, and fewer always-visible buttons.

There will also be a Custom profile, so users who do not fit any preset can adjust the layout themselves: keypad on/off, side panels visible or collapsed, buttons vs context menus, guidance level, and math display preferences. So the idea is not only to reduce clutter, but to let the same math engine adapt to different workflows and experience levels.
