16 pages of info... TL;DR

Just a few things off the top of my head.
- Smartlink would be awesome, some way for a TM to talk directly to their gun without needing Eyeware or implants.
- TM Foci. Somebody already wrote
some house rules for some, basing them almost entirely off Magic Foci.
- More Sprites, there were quite a few variants in the SR4 stuff.
- Reduce Fading on pretty much everything. Otherwise you have to Edge every
Puppeteer use to avoid killing yourself in the process.
- Clearly define things like
Resonance Veil and
Resonance Channel.
- - Res Veil says "something happens" which could literally be anything. I've had some GMs admit they think it's within the realm of possibility for me to convince an ATM it "thought it saw" my bank account full of money, so it would gladly fill my Credstick to the top. Now I'm walking around with a Credstick full of cash that came from nowhere. Or at least being able to convince the cash register at checkout, that the empty Credstick you slotted is really full of funds. You get the basket full of goods, and the store is unaware until after you've driven away and dropped the power.
- - Res Channel feels somewhat wasted. There's so much fluff about the Resonance, how it's some mystical layer of data that connects all digital devices together. Which, if you were directing traffic through the Resonance, would theoretically mean you could communicate with devices anywhere. Perhaps even connecting with devices that have their usual wireless communication disabled. May be an interesting idea... even if you had to raise it up to an Echo. I'd definitely take an Echo that let me connect to devices that are otherwise "offline".
- I saw that some others had mentioned it already, but the Echoes need a buff as well. Nobody wants to go through the ordeal of Submergence, paying all that Karma (even when you account for the typo in the cost) if all they're getting is +1 to a single ASDF rating.
