It means: we know our stuff and will always be there to help → you can rely on us!
In the end it's the support that makes the product suitable for Enterprise use and Midori's support is really quick, helpful and professional.
However what impresses me most is Midori's customer support: Szilvia's unfailingly patient and friendly assistance to all of our queries is a breath of fresh air.
Typically, one of the primary reasons for avoiding third-party components is anticipating you'll will have to cope with slow and uneven customer support, but the Midori support I've experienced has been first rate.
The app itself works flawlessly and is extremely flexible. Most of the reviews I read here say that, as well, but what many of them do not say is how professionally Midori treats its customers.
They have great documentation. Relevant and easy-to-follow examples had me creating my first reports within minutes.
