Just what I needed

I mainly got this for the resistor codes but I have no doubt I'll put the other tools to use too. It's a nice little app and I'm happy to support Adafruit software!

Cool app. Latest update is excellent.

This is such a great app. I have an awesome project i made to take to sporting events. It's sweet. But... It is SO hard to pair in a crowded environment. Everyone and their dog has at least one BLE device on them now (anyone reading this will for sure). Their is no filter or way to sort devices to find the adafruit one. This would be a very welcome addition. Filter by name, UART only, sort, something.

Update: they added filtering and it is awesome! Much appreciated, easy 5 star rating now.

The new 2.0 version has a flaw when sending intensity string to ble device. Previous command was #FFF (RGB intensity) now red and green intensity works normal but blue intensity is only 30% brightness or off entirely! How can I get previous good working version!!! Btw software version changes should have a "revert back" button so when issue like this occur, users can get the last working version!!
Please fix!!
