Feature: Show/Hide Screens

[nwittwer]

Ability to hide or show a screen on the canvas. Most likely makes sense in the right-click context menu for the sidebar and when clicking on a screen.

1. Add menu item to context menu to Show or Hide screen (should change title based on its current state)
2. Add Vuex Store property to artboards that defines their show/hide state
3. Add Vuex Store methods to toggle the state of the hidden/shown artboard

Hi, can I take this one? :)

[nwittwer]

@emilkowalski Sure! :) Let me know if you run into any issues getting it running or finding things. Try branching off from dev.

@nwittwer I have managed to implement this feature, but forgot to branch off from dev, that's why I closed the pull request. I've branched off from dev now, but when I run yarn run dev, im getting an error:
"Cannot read property 'length' of undefined"
It's about artboards.length.
Had no issues working from master.
Any idea how I can fix it so that I can implement my solution? :

@emilkowalski Sorry about the late comment about branching from dev, I'll try and update the readme to make that more straightforward.

To fix that other issue you mentioned, try clearing your local storage by opening the DevTools > Application > Local Storage > file:// > and then delete the Reflex key. After reloading the app it should work again. I'd like to add an OS menu item to easily delete this, because I think this error happens when the localStorage data model has changed. It is a migration issue. Please let me know if it isn't fixed after that. UPDATE: I've detailed this bug and an idea to deal with it here: #165

I haven't been able to try it out yet, but I think your solution seems good! Please go ahead and try the fix and then make another PR :)
