Small listbox, meaning of two entries is not clear

Version:           2.1.1 (using KDE 4.7.1) 
OS:                Linux

Hello,

to tag a person on a photo, I have to use bot keyboard and mouse to select the keyword from the listbox.

It would be very nice if the workflow could be refined so that one could tag using the keyboard (entering a new name, hit enter) or mouse (type the start of an existing name/keyword,  click the correct keyword and click on "OK"). See below for details.

Kind regards,
Michael

Reproducible: Always

Steps to Reproduce:
1. Draw a new face tag or select an automatically created face tag
2. Click on the edit box
3. Type a name, list box with matching keywords appears
--> List box is very small, see attached screenshot. The meaning of both entries is not clear

4. Click on an existing keyword
--> This does not complete the entered name

5. Complete name by keyboard
6. Hit enter
--> Does not enable the submit button, I must click the listbox again

Alternative:
1. Start typing
2. Ho down with cursor and hit enter on existing keyword
--> List box disappear
--> Input box is empty
--> No name/keyword is stored


Actual Results:  
- The listbox is useless if you wish to select existing keywords.
- The listbox is too small.
- Hitting "Enter" does not save the current entry.
- Mouse select does not select the current entry

Expected Results:  
- If the enter key is hit, the current entry in the input box should be saved, maybe dependent on the preferences (save changes in the right pane without notification, IIRC)
--> Start typing, select entry with cursor keys, hit enter. Finish.

- If an existing keyword is selected by mouse, the input box must contain that keyword, and the submit button must be enabled.
--> Start typing, select entry with mouse click, click submit (or hit enter). Finish.
