I like the new briefing pack Feature.
but is it really necessary to ‌also include NOTAMs about Schengen restrictions and tons of dangerous Areas in Syria, Sudan , Libya and lot more even if I plan a flight all inside Germany? Or to Austria ?
Maybe These NOTAMs are not tagged with a certain Location and one can filter out those records‌

You should be able to hide NOTAM which you deem not applicable to your flight.

If Sky‌Demon is showing them to you, it means authorities within Germany or whatever country you're flying in, think it is important for you to see that NOTAM. That's why the NOTAM have been designated as covering the country you're flying in. This isn't a fault in SkyDemon.‌‌

I'm interested in the same.  I want to see NOTAMs that affect my given flight. 

‌Example, If I'm flying from Wycombe to the Isle of Wight, I don't need to be aware of every crane erected in London.  Any way to filter these "after the fact"?  Meaning you've (SkyDemon) have displayed all NOTAMS as legally required, but I don't care about a 167ft crane near St Pauls nor will I accidentally fly into Syrian airspace on lunch flight, so I just want to see stuff that I will encounter.
‌

I think the SkyDemon team are between a rock and a hard place here. The NOTAMs shown include so much irrelevant junk for most GA flights that it's easy to miss the new 2,500' TV tower in among the multitudinous 200' cranes, but automatically filtering out NOTAMs leaves SkyDemon exposed to claims in the event that a filtered NOTAM results in an accident. The real solution is for the NOTAM system itself to be improved to allow filtering to be performed accurately and reliable, until then I fear we are stuck with manually hiding NOTAMs which we (as pilots) have reviewed and made an informed decision to hide.

H‌aving said all that, I do wish it was possible to hide any NOTAM - some seem to be marked as persistent - and for the list of hidden NOTAMs to automatically sync between devices.
