Main changes:

• 2X parallel micro SD slots
  - 1. card MCU
  - 2. card SENSOR
  - you can also use 2x MCU and communicate over I2C
  - no care where is MCU or sensor, they are parallel
• Display is direct on board not on module
  - WHY? until January I ordered on 4x on ebay by picture, I received 4x different display, with different pinout
  - you can put card from top side what is more practical
• I will focus to keep all compatible with display module version, which is more DIY friendly
• I think about microUSB for charging and add option for lion battery instead CR2032

This is preview for board with 2 micro SD slot.
