increase the number of active shared prototypes and design specs for free users
I understand why the limit exists and I'm ok with the presence of a limit in the active shared prototypes and design specs.
Given that nowadays almost every develop platforms have quite large free tiers (Azure DevOps, GitHub, TeamCity, AWS, GitLab, and others), the limit of one active project don't fit very well with the free tiers of those dev tools.
I think that a bigger limit could be really really appreciated from hobbyists, freelances and small startup (which are the users of those free tiers) who can do the upgrade to a paid plan when their business permit it.
To me 5 or 3 active projects could be good compromises.
