Enable drag and drop for files in the connection form

Bug Report

Current Behavior

Code/Gist

Expected Behavior/Code

When setting up a new SSH Tunnel Connection with Use Identify File, the file picker automatically turns off "Show Hidden Files", thereby blocking access to .ssh. There is also no drag & drop option available, so key files inside .ssh aren't selectable. This pretty much makes this extension unusable for remote database connections through SSH in Linux.

Environment

• node.js / npm versions:
• OS:
  Xubuntu 20.10

Possible Solution

Do not automatically turn off "Show Hidden Files" when opening the file picker.

Hi @nathanielfink - thanks for reporting - unfortunately I don't believe this is something we have control over with the open file dialogue. Looking at vscode's open file options documentation it looks like we don't have an option to specify that default.

On mac it's possible to show hidden files with command+shift+..
Maybe there's a similar way to show hidden files inside the file picker dialogue on linux?

I do think we could enable drag and drop for files so we can leave this open as a feature request for that.

For context here's where we use it in our code:
