aljo_petek You can call me weird, but I have my own opinion about huge dialogs with settings like this for such a simple function as a slideshow. It is against ideology I am using while building this application. FastStone is not the worst case though, have you seen slideshow settings dialog from very similar and also quite popular applicaiton IrfanView? Here it is:
If there is a way to avoid settings dialog for some funciton, I will avoid it. And what I can tell from talking to many users - simplicity turns out to be a feature of Tonfotos most user really like. With that said, there are many other, more intuitive ways to change the way feature works, without using monstrous settings dialogs.
However, going back to original reqest - disabling “pan and zoom” feature during slide show - this is the first time some one requests it. I guess I will need to wait for more feedback on that topic before assigning this a priority.
