I would like to use the TinyScreen as a remote display for an ESP8266 and therefor both devices (TinyDuino and ESP8266) should communicate via I2C. Unfortunately the protoboards have only one connector so I can't use the protoboard and the TinyScreen in combination.
Is there any hope that there will be another protoboard with two connectors ?

Actually there is a solution for this now, we have a new protoboard that has an optional top connector.  You can find it here:  https://www.tiny-circuits.com/tiny-shield-proto-board-all-163.html

Thanks,
