+'''Heuristic analysis for ChatSecure'''
+''1.	Visibility of system status''
+*Sending messages: The lock kept open, when I clicked on “start OTR”, so it didn`t work and I don`t even know why. (Description box needed!) I later realized that it only worked when the person I was sending the message to was online. I would like to send a secure message to an offline person, but don`t know how. Need I download the OTR Keystore then? This friend also didn`t get my messages at all and I didn`t know that, because no error sign occurred. (See “error prevention”)
+*Add contacts: When I added a contact, he showed up in the contact list twice. I deleted one of them… later “both” accounts were gone, so I fully deleted the contact by accident.
+''2.	Match between system and the real world''
+*Sending messages: I have no knowledge in computer science, so I would like to have a little explanation about what OTR or this OTR Keystore is. I would like to read easier words, like “start secure messaging” that don`t make me wonder what I am doing. Furthermore, I only found the “import OTR keystore”-button just by accident!
+*Add contacts: No problem.
+''3.	User control and freedom''
+*Sending messages: All ok.
+*Add contacts: All ok.
+''4.	Consistency and standards''
+*Sending messages: No problems.
+*Add contacts: The touch screen doesn`t work sometimes, when clicking on “Add a contact”.
+''5.	Error prevention''
+*Sending messages: I didn’t know my messages weren’t sent at all.  My message window was all empty. I couldn`t see that I did not send my friend something nor could I see her messages.
+*Add contacts: I didn`t know, it would delete the “right” account, too.
+''6.	Recognition rather than recall''
+*Sending messages: Didn`t understand the box that plopped out, when I wanted to import the OTR keystore. (And don`t know what it is for, by the way.) It was only open for a few seconds, so I couldn`t read all of it. After I read it 3 times, I still didn`t found this file, the window wanted to lead me to.
+*Add contacts: After typing in the name in the contact box, I wanted to click on “invite”. For that I clicked in the red box below, because I intuitively thought, I would come to the interface before. Maybe it is better to place the “invite”-button somewhere in the red box, because you won`t have to click the keypad away then.
+       the "invite" button is unseen		             the interface before
+''7.	Flexibility and efficiency of use''
+*Sending messages: No problem.
+*Add contacts: Everything ok.
+''8.	Aesthetic and minimalist design''
+*Sending messages: I clicked on someone on the contact-list. The message window opened and I typed something. So now, to write another person, I needed to slide over many people before I got to the “general” contact list, where all friends are listed. I think having the general list in one slide is way easier.
+          The “general” contact list
+*Add contacts: Is ok.
+''9.	Help users recognize, diagnose, and recover from errors''
+*Sending messages: See points 1 and 5.
+*Add contacts:  See points 1 and 5.
+''10.	Help and documentation''
+*Sending messages: As said before, I would like to have some explanation what an OTR is. Or just easier words and an extra field for “how it functions” in the settings.
+*Add contacts: Everything ok.
