The ability to create custom fields with ease or no coding at al! Custom Fields are great because I can set them up like any other field but they're not limited by type which makes it easy if you need multiple types as well.
Not much dislike about this software- very simple yet powerful toolkit perfect fit into our small team needs! We use these tools primarily within salesforce so far we have had little issues outside sales force integration.- Ability to track leads through out pipeline via different stages such as qualifying stage etc.
