Issue: Explanatory gif is better presented as a video

[nav9]

Issue you'd like to raise.

There's [this gif](https://github-production-user-asset-6210df.s3.amazonaws.com/10168/284664286-fe5dd3c0-b3cc-4701-98d3-0280dfbcf26f.gif?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=AKIAIWNJYAX4CSVEH53A%2F20231209%2Fus-east-1%2Fs3%2Faws4_request&X-Amz-Date=20231209T155110Z&X-Amz-Expires=300&X-Amz-Signature=fde7c29da2aff726709f826e059b8e58af94e27de7e5d9a9fecb1782aa0039ac&X-Amz-SignedHeaders=host&actor_id=0&key_id=0&repo_id=619959033) on this page, which is difficult to follow for two reasons:

1. It's too small.
2. After watching it, when I wanted to actually try using the feature in my installed GPT4All, I wanted to see the first few steps shown in the gif, but now I have to wait until the entire thing finishes displaying, and each time I watch it, I don't have the option of rewinding back to a step I didn't quite understand or see clearly.

Suggestion:

So please provide videos with a nav-bar, instead of showing such instructions as a gif.

ps: It'd also help to name "collection" as "folder" or at least show it as "collection (folder)", and also have a separate "Browse" button for folder selection and a separate "Browse" button for file selection. I initially ended up selecting a folder for the file textfield, and then kept wondering what on earth "collection" is supposed to be. There also seems to be an issue of not being allowed to select the leaf folder. For example, if I have a folder /home/nav/someFolder/data/, GPT4All's interface allows me to only select until /home/nav/someFolder/.
