Suppress the switch panel button

Congratulations, you have created a wonderful calculator; I use it on a daily basis.

I have a request, is there a possibility to remove the switch panel button (the one is located below the point key). I have to be very careful whenever I want to press the point key to avoid switching panels, I believe the swipe option is faster and elegant.

Thanks in advance

Thanks. I am glad you like it. I have also found that I sometimes hit the page control at the bottom of the screen when aiming for the period. In fact, it happened once or twice in the demo video.

Disabling it is easy enough. During initial development, it was the only way to switch when I hadn't implement swiping. Although the control isn't that useful today for switching between the pages of buttons, I think it still has some value to indicate that there is another page of buttons.

Regardless, I will experiment with some different options and see if I can include a "fix" for this annoyance in the next release. I am hoping to get a v1.1 to Apple for review in the next week or two. Thanks again and let me know if you have more suggestions.

It is possible to have a touch feedback? ( vibra )

That is a great idea - to support some haptic feedback on button presses. I will add that to my list of features to add. I am working on a fairly major update with UI changes and support for the Algebra operations (collect, expand, FORM, etc) so this feature request will probably not make that release. Perhaps the one after that.
