How will we support Scratch 2.0 projects that have multiple "current ()" monitors?

[fsih]

In Scratch 2.0, it was possible to have monitors for "current second," "current minute," "current hour" etc. simultaneously. In 3.0, they will all share 1 monitor. We should figure out how projects with multiple monitors will behave in 3.0.

• When I open the project in 3.0, will all of the different monitors still be present, or will they all merge into 1 monitor?
• If I change the value on the dropdown on the "current ()" block, will all of the monitors change? One of them? Will a new monitor appear?

Currently, no monitors appear.

I think it should behave like Scratch 1.4's (sensor[v]) block in that it makes a new monitor when the dropdown is changed and the checkbox is ticked.

In 3.0, they will all share 1 monitor

Why

@heyitsmeuralex In Scratch 3.0 it's only possible for each block to have one monitor (not multiple). There's not a big "why" design reason for this - it's just an effect of how it was programmed. (NB: I don't actually know how monitors are programmed, I'm just guesstimating this. :P)
