Hi @erit,
thank you so much for your kind words. It really means a lot to us 
Even back when we were Podio users, we always felt that conditionally shown fields can be a real game changer. And honestly, with the new Record Experience, we feel like we are only at the beginning of discovering what this can unlock. We still believe this will become even more powerful with everything that is ahead.
About the Checklist field: it is currently one of the last field types on our list for the new Record Experience. The reason is that we want to rebuild some important foundations here, so we can deliver a really great experience, for example creating checklist items from everywhere, linking them to other records later, private checklist items, and more.
That is why @CarsonRedCliffLabs suggestion is actually a really strong one. Until the Checklist field is available, using a Relation field can be a very good alternative. With the list view for related records, it already gets very close to a task list. You can also work with status, date, and soon member fields inline.
We are also thinking about inline creation for Relation fields as part of this topic, so it could become a real alternative to checklist fields, with the extra benefit that you can filter in the related sub task database, use automations more easily, report on the items, and so on.
So yes, this could really be a good path for your remaining apps in the meantime. And the Checklist field is not too far away anymore. We are talking about a few months, and as mentioned in my post above, we are currently aiming for late summer or early autumn for the full switch to the new Record Experience.
Thanks again for your support, your feedback, and for using Tape. It is amazing to hear that we could excite you with the new Record.
Have a great weekend!
