Note: the same things that are criticized here were also criticized with respect to the navigation column of the desktop version (cf. ).
**Steps to reproduce:**
Click on button to open the main menu
- once when having been at the the startpage/inbox before
- once when having been in the "contacts" area before
- once when having composed a new email before
**Actual results/Problem:**
A changing **number** of options - 7 after having been in the inbox/mail area before VS. 6 after having been in the "contacts" area before VS. 5 after having composed an email (see screenshots!) - are presented, dependent on the are in which you have been before, **and** the buttons are presented in a different order!
--> Inconsistency confuses user and leads to less efficiency since more time is needed to operate the system because the user always has to "re-orient" himself on what options and in which order are //now// available to him (he can**not** //learn// to operate the system by internalizing the //places// of the buttons and then at some point click on them more or less "automatically" just because he/she knows where they are)!
**Expected results/Solution:**
The number of buttons/areas available is **always the same**
AND
The buttons/areas available are always in the **same order**.
