Switch to Score tab immediately when opening a score, to make it seem more responsive

Your idea

Currently, the order of operations seems to be:

1. User clicks score to open it
2. Processing processing processing processing...
3. Score tab appears, with score loaded

The lack of visual feedback after step 1 makes it feel like the app is slow to respond to user actions, and you don't really know if it's doing anything or that you have to click again.

I propose to change the order to:

1. User clicks score to open it
2. Score tab appears, albeit still empty -> the immediate visual feedback will make it feel more snappy
3. Processing processing processing processing... (perhaps with progress indicator in the future)
4. Score appears in canvas

Problem to be solved

I think this would be an easy way to make the app feel snappier without spending ages on trying to improve the actual performance and then come to the conclusion that there is not much that can be done because opening a score is simply a big operation.

Prior art

No response

Additional context

The only potential downside that I can see is: When there is an error, and the score cannot be opened, that would mean that the user would end up with an error message on an empty Score tab rather than the Home tab. But that's really a non-issue, IMO.
