XnView Software

First of all thanks a lot for this great tool! I have a small suggestion for the fullscreen viewer:
Would it be possible to add a function where the user can limit the zoom? I think it is not useful to zoom out and the screen is not used completely used in both axis and at least one should be used ...

Thanks, {EXIF:Exposure Bias} was the command I needed. Where can I see all the possible commands?

I know, I edited it. But there are only a few examples and not the whole possibilities. As mentioned I'm searching for Exposure bias value and some other Exif data to show.

Is there a list of all info that could be shown in overlay? For example I'd like to show the Exposure bias value.

I'd also like to see this. The Google map lacks in details and contrast. OSM or OpenTopoMap would be really nice.
