Failures from transactions need more of an explanation. Or a queue of transactions should be displayed somewhere

[JorikSchellekens]

The failures of a transaction take over the whole side panel and their description can be improved from "runtime error"

What would be very cool would be a list of pending transactions and their state underneath the testnet selection

-----------
tesnet
local
etc
-----------
1. Deploy transaction 🟢 
-----------
2. Invoke transaction 🟤 
-----------
3. Invoke transaction 🔴  -> error on click / hover
