- What browsers show this problem?
Google Chrome - Please share an example project (if possible).
Can't, because when you reload project it is fixed. - Describes the steps to reproduce this issue.
Create a custom block with a local block or script variable. Right click on the block and SOMETIMES there is an option that is the variable name. If you select it, it shows the variable on the screen/canvas. You can now never hide it no matter what you do, and must reload the project. This has also happened without the student selecting to display the local variable. - What does Snap! currently do?
Keeps these variables displayed on the screen and you cannot hide them. - What should Snap! do instead?
Have an option in the right click menu to hide them, and/or have the "hide variable" block actually hide the variable.
The variable option only shows up while the block is running. Drag the watcher to the block pallette to get rid of it.
