Wait to show "run" buttons of sidechains until mainchain IBD is completed?

The sidechains cannot connect to the mainchain until the mainchain has completed initial block download and is completely synced up to the main chain tip. If someone starts the sidechains when the mainchain is out of sync they will not be able to do anything and may need to restart / manually re-enable networking once mainchain has synced up.

Instead we could wait to enable the sidechains until the mainchain is synced up. What do you guys think?

Sounds good to me.

Is there some sort of callback emitted by the mainchain when this occurs?

This is a great idea. After spending more time in the Launcher this makes way more sense. Probably as simple as putting whatever logic responsible for greying/ungreying the buttons inside a conditional that checks if the IBD is done. I'll put it on the list of things to do after the wallets.

Eventually, I think the launcher should show IBD percentages for each chain

Then it will be something the user understands -- downloaded 100%, synced 100%

They will know to wait, until the numbers are 100%

The launcher can display "0% synced" for the sidechain, if the mainchain is below a certain height
