It would be very helpful to our users if we could link some HubSpot data (like clients) with external apps and websites, but in a very basic and simple way (not by programming extensions).

Idea is to use custom fields for it, of type “calculation”. Calculation would basically be a string/variables concatenation. If resulting field is detected as link (i.e., starts with “http”) HubSpot UI would display it as a link, not as a text/textfield.

Example of usage can be: on our customer sidebar, we want a link to our accounting app, to a page of selected customer. We would create a custom filed that concatenates “…accounting.com/client?clientId=” and variable $clientID. Then we would put that custom field to customer sidebar where it would be displayed as link.

So, two basic features are needed for this:

1) custom filed - calculated filed needs to support string concatenation, not just aritmetic operations

2) at least calculated (noneditable) fields should be displayed as links if link format detected (http/https). Ideally, all text fileds should behave similar.

Currently, partial workarround for the above is only:

1) use workflows to create calculated links (but the problems of them not being displayed as links remains)

2) program extension (way more complex)
