Hello,
there is a huge group of Attiny85 lovers and the PGM-11801 is a great tool for it. But its idea of minimalistic requirement to program Attiny85 with I2C devices is completely useless 
As the chip needs to be removed from the programmer. Most of my projects contain I2C OLED screen. And designing some display layout requires countless amount of change-upload cycles. With attiny85 you need continuously remove and attach the programmer. It became some kind of an annoyance that lowers motivation to develop some stuff. I know, that I can use other boards like Arduino Nano attached to for prototyping before moving to attiny85. But I use libraries, that are designed especially for attin85.
A simple solution could be to redesign PGM-11801 to contain a physical or logical switch to separate programmer from the Attiny85 with a push of the button or physical switch. So it will allow keeping all stuff connected to the chip via prototyping pins. So no separate breadboard and jumper wire jungle needed. So we just can make our ideas come true without hassle while sitting on the comfy sofa or travelling by train or car.
