"Arduino Examples" showed twice

[reyang]

Plug in the DevKit, unplug it, then plug in again, there will be two "Arduino Examples" tabs opened.
Expect only one.

@reyang which OS are you using ?

I try on my win10 , but not repro this issue

[reyang]

Microsoft Windows [Version 10.0.16299.248]

I can repro this issue too.

@Sneezry Can you help to fix this issue ?

This issue happens when no document open in vscode. Arduino Examples page is open in the second column

https://github.com/Microsoft/vscode-arduino/blob/0bb2b7392e67b2f59a67382a210fbbd2095a1206/src/extension.ts#L113

When on document open, vscode will open it in the first column, and when we re-plugin DevKit, vscode open a new one in the second column.

I have post an issue here: microsoft/vscode#46161

Since this is not a issue from our extension, and VS Code planned to fix it.
Close it on our side.
