Prime feature request

[Stefan Dröge (Germany)]

I guess the development team is still pretty busy at fixing bugs, but nonetheless I want to start a (incomplete) wishlist for future firmware versions. I hope HP will take some of the ideas and include them.

1. Insert constant as symbols, not as numeric values. (This is already done for Pi, i and e, so why not for the other constants?)
   
2. Say I want to insert a constant with its units. At present the option to insert the constant with units is reset every time the "Unit" menu is opened. But IMO the menu should retain the setting.
   
3. Undo & Redo function
   
4. Select text with Shift + D-Pad-left/right
   
5. Tabs in CAS and numeric view (or make a CAS/Numeric "App" so that copies of this App can be saved)
   

(The numbers in front of each item are NOT priorities. They are just for easier discussion of each item.)
