Top Con

AmbitiousKratos's Experience

Bloatware. Slow and unreliable (too many DB crashes) See More

Top Pro

Sophisticated address book

Each contact can have their e-mail address, phone number, location, photos and associated URLs added to them.

Top Con

Klu

Unfortunately, all interfaces of roundcube look very old. I hope there will be a progress soon, Google Mail and Outlook Webmail should be the role models here. But also Yahoo mail offers an intuitive design. If this open source software should survive, it must be completely renewed and bring up to new standards. See More
