Currently, if I want to add a testnet network, I need to do quite a few steps, specifically, I have to go to the website https://testnet.keplr.app/ or https://chains.keplr.app/ then search and select the network.
I had the idea that there would be a checkbox showing the testnet, once it was ticked, I could find it and add it right to the wallet.
The testnets will be validated and approved.
