Thanks for reaching out! The current version of Leadin downloadable from Leadin.com is our most up to date v4.0.0 edition. Version 4 is almost a complete rebuild of the Leadin tool to provide a much faster and more stable version of Leadin which we can scale quickly. The version in our documentation is our version 3.1.9. At the moment we are working hard to rebuild all the functionality of v3.1.9 into v4.0.0.
?Currently the main differences between v3 and v4 are that v4 only syncs with MailChimp for email, but the other ESPs Constant Contact, Campaign Monitor, GetResponse, and AWeber will be coming very soon. The most notable difference between v4 and v3 (which you have mentioned) is that the ‘Power Ups’ menu is gone. This is actually not because the power ups themselves are gone, we have actually just built them directly into the v4 plugin so the functionality should still exist for you (except for those additional ESPs for the moment).
?
In v4, you simply navigate to one of your form tags on the sidebar of the Leadin Contacts screen and from here you will see ‘not pushing to MailChimp’ in the top right. If you click on this you will then be able to check the lists you would like to push these contacts into.
I hope this helps. Let me know if there is anything else I can help with.
