🐛 Need a more modern browser widget #21
Description
In #15 I added an ipytree.Tree browser widget, but it has a bug that the open/close icon doesn't always render on the first pass. Since ipytree was last updated in 2022 there's no reason to think this will get fixed.
A more modern approach, like building something from scratch with just ipywidgets (or perhaps anywidget) or using ipyvuetify.Treeview (or some other solution) is needed. I burned some time on ipyvuetify.Treeview already, but couldn't manage to get per-item customization of things like the icon/selectability, etc.
