Hello, and thank you for the rating. The Image Pop-Up is instantaneous because it was designed that way, and I've kept it like this since it's proven very useful when browsing many mods or images. That said, you're right that an accidental hover shouldn't trigger it — I'll add a configurable delay in a future version.

About the outdated mod warning: this is a new feature, and I hadn't considered adding an option to disable it until now. I'll add that in the next update.

In general, most functions are active by default because many users install the extension without knowing how it works (or that it can be configured), and end up thinking something is broken when a feature is actually just disabled. Defaulting everything on makes the extension's value visible on first use. That said, you raise a fair point that some features might be intrusive enough that they should start off, and I'll reconsider this for a future release.

If you have more feedback, feel free to reach out on the extension's NexusMods page — I read everything there. Thanks again!
