Create Plans features as choosable custom fields

Create a plan with choosable features via custom fields.

When you create a plan, having the possibility to choose from potential features provided by the admin configuring membership pro.
It would also be nice to be able to have access levels per feature and make it configurable in admin of membership pro


Plan A:          Plan B:           Plan C:
- feature 1     - feature 3     - feature 1
- feature 2                          - feature 2
- feature 3

Here is my 5 cents about what is missing right now:

1. Plan Custom Fields. To render custom fields output on all plan views in menus/modules. Can be used for plan features, additional images, ratings, signup button text, discounts, etc...
2. Extend Shortcuts(tags) functionality. To retrieve any plan related information in articles/cutsom_modules/content_fields by setting plan id or alias and what information should be retrieved, example: {membershipplans ids="12" price | field_5 | field_alias | signup_url | plan_alias | category | upgrade_options | etc...}. I might be wrong, but "membershipplans" can't take plan alias as an argument, only ids.
3. Field Groups for plan and user fields. To organize fields, similar to joomla's fields.
4. Joomla Content Field type MembershipPro. To be able to include bits of plan info into articles, similar to shortcuts.
5. API access for everything mentioned above.
