The S3 plugin is a bit strange as there are a few variants as a lot of them appear to be forked and then abandoned again.

We were originally going to look at redeveloping our own plugin but found this one worked for our needs and still works in the latest version:

Any plans for HEIC support? I understand it's not supported by browsers yet but it would be useful to have some way of converting file uploads to jpeg as we're starting to find this an issue with iPhone users.

Our existing forum structure includes an extra level, which we use as a section heading. While this works this prevents our theme from showing the subcategories underneath.

I have tracked this down to the helpers.trimChildren function, which sets the children variable to undefined as a way of limiting the depth. As we need as extra depth level is there any way of overriding this function without having to resort to modifying core code?

You can see in these screenshots. The first screenshot is how it looks normally and the second is how we want it to look.
