New section for models and plots in variable pane

[ntluong95]

In the variable pane, as far as I know there are 2 sections now, one for dataframe and others. It would be beneficial to have more sections, for example a separate space for models and plots. As it is common to produce many models and plots, and when there are two many objects, it is hard to navigate

Thank you for this feature request! 🙌

I do think it will be tough for us say what objects are/are not models or plots, other than for some very broadly used packages. Let's use this discussion to capture the ideas folks have on this and how important this may be. Thanks again!
