Multiple versions of variable viewer window can be opened

[bajhuman]

The Spyder variable explorer allows you to open a variable window even if that same variable is already open. Is there any plan to implement the variable window (i.e. a dataframe) as a singleton instance. This would undoubtably be very welcome and increase productivity. At the moment it is possible to be looking at an old version of a variable without knowing.

• Spyder version: 5.4.5
• Python version: 3.9.0
• Qt version:
• PyQt version: 5.15.9
• Operating System name/version: Windows

Hi @bajhuman thank you for the feedback! I'm not aware of a plan for restricting the possibility of opening multiple editor dialogs /variable windows instances for the same variable 🤔 What do you think @spyder-ide/core-developers ?

Also, related to the editor dialog displaying an old version of a variable, a new feature was recently added to the editors dialogs to refresh their content (#21312) which should improve that situation (that new feature will be part of Spyder 6).

Closing due to lack of response and since the work done at #21312 potencially could help with preventing seeing outdated variables
