You’re right, a preview of a MindNode file, especially on a smaller iPad screen, is not very useful.I wasn’t so interested in getting a preview in DTTG as I was having the ability to open it in MindNode and make changes to the file in DTTG which would sync to DT.
I appreciate everyone providing insight into how to get that done! It just seems a bit odd getting that blank screen when you download a file …
