Various gallery features that would be useful.
It would be nice if:
Metro style can be selected in the layout option, with individual settings
Album creation with a folder structure
Upload alternative image for hover
Filtering with Category
Tablet behavior would also be very helpful.
An example from the plugin here - this one will probably not be around for long, there have been no updates since 2018 and the website no longer exists. It is time to change, but these functions should be fulfilled :)

It would be great if you could do that as well.
