Hey Dima,
1. Why should it search inside categories? The categories are a filter, they are not part of the "search hotspots" feature.
2. That's intended. I've tested a lot of options and the problem with zooming in is that you lose your focus. If you click on hotspots 1, then we zoom in. Then you wnat to click on hotspot 2 and we zoom in again and jump to a completly different location. This is really confusing. That's why I've decided to remove this option and leave it as it is. If the user wants to zoom in, there is a zoom in button in the hotspots. Or he can just zoom in with the mouse.
Regards,
Daniel
