The information you need is in the AIP (as you mentioned) so it is one or two clicks away in SkyDemon at all times. I do not believe it would be beneficial for us to duplicate that particular information from the AIP. As far as I'm aware, the competitor you mentioned does pretty much the same thing.

Dear 

Did you consider to add some more information when planning route , some kind of pre-flight briefing ?
Let's say that you are planning route , when filling maybe there will be possibility to display information that for ex. on this airfield you need to arrange SLOT for arrive and there is PPR required , if handling is mandatory then you will receive contact to handling agents etc.
I know that everything is in AIP but if you will receive this info you don't need to spent time studying AIP .
I have tested your competitors RocketRoute and they have information like this.
I know that there shoul be propably one person resonsible only for that and need to check and update all this information but maybe we as a pilots can post information like this to help other pilots.

thank you
