My company just recently switched to HubSpot, which is great from a sales and marketing standpoint. However, I'm very surprised to see that you only allow very simple property values (that are not predefined) on CRM objects. I can imagine that a lot of companies would want to register information on their objects that do not fit either single- or multiline text inputs.
I propose a multi-record property that allows users to input multiple values. It could be composed of 1-many single-line text inputs or 1-many multi-line text inputs (or other variants such as integer, float, emails etc.).
From the CRM object view after inputting one value, it should reveal a "+" button that would allow you to input another.
Adding property validation would also be a great addition!
