I made a python panel using chatgpt that allows you to save vex from a wrangle node into a python panel. You can give the snippet a name and description, organize into groups, import snippets from a .json file, export snippets as a json, modify and delete existing snippets. Most importantly you can select snippets and apply it to a wrangle node when you need it. I've added an image of what the panel looks like. It's a very basic panel but might be useful for some.
The snippets are automatically updated to a json file in the houdini home directory called vexsnippetspanel.json , this should auto load/update when you use the panel. If you don't have the json file it should create one when you save your first vex snippet.
I have included a sample that chatgpt made for testing "vexsnippetspanel.json" just put this is the houdini home folder and it should auto load when you open the vexsnippets panel. You can open both files in a text editor and modify them also if you like.

If anyone has tried it or has any suggestions leave a comment.
