working with the web interface I have found some characteristics that I think can be improved, particularly:
1) In the list of the content of the mail folder it misses among the attributes of visualization the "To" attribute; very important thing when I visualize the Sent folder.
2) Not all the characteristics of visualization can be reorganized in width (for example Subject).
3) From the window of creation of a new e-mail I cannot visualize all of my contacts but I obligatorily have to make a search for text substring; besides if the search gets too many results I get an error (for example looking for a*). Even if you decide to bring forth this logic for the searches I allow me to suggest to replace the aforesaid error message with a result of the type "too many found object".
Thanks for the attention.
