Excluding collections / show multible ones

I would like to be able to pick multible collections / Exclude collections from the “My coins” Page. 

The World map is a really cool feature, but it can be “ruined” if you have a ron of crap coins from one country. Most of us have that with our home country. 

I have a ton of German Pfennig coins which adds a lot of coins to my german coins, so i have a Dark Red Germany, and everything else only blue and green. 

So it would be awesome if i could put them in a separate collection and basically “disable” them from the collection. 

I know its a picky problem, but im sure most of us have this unbalanced worldmap. 

There are requests to change the logarithmic scale that we have right now to allow lower amounts to show more against outliers.

There is also the types view which would eliminate the large amounts of same types and if you have a ton of doubles I would put them as swapping coins. Those can be filtered out.

OK, but what about stuff like Notgeld? I got quite a few of those too. ~100 different ones. I would be happy to be able to see that map without those. I don't want them to not show up at all of course. But it would be cool too see that. 

Same goes for other stuff. Like countries who produce a lot of commemeretives. If you bought a lot of coins with 80+ different Polish, Canadian or Russian commemeretives, then you have a big red blob. And yes it technically shows you exactly what you have and how it's distributed. But having at least the option to turn off specific collections would be cool. 

If you guys don't want to implement that, than it's okay. At the end it was a suggestion and you guys decide which features get implemented and not. I kinda get the attitude you guys have with: “but can technically do it that way or like this” similarly to the suggestion with tags on Coins. “you can add a comment”. Yes I know, but then the comments on my coins would look like this: “ship, queen, BigCoA…” 

At the end of the day you are the people who implement stuff, so I get that you don't want extra work for something that can already be kinda done with other methods. 

I hope I didn't sound annoyed, mad or harsh. I know it may read like it, but it's not meant like that. 

Huge thanks to the team behind Numista and that you can keep this great and especially free website working!

Cheers 

I don't have any problem with colours, every colour - except of light grey - is a good colour.

But yes, I would enjoy a solution, where I could organize and publish parts of the collection and where I could use the database and tools for private parts also.

As far as I understood, i have no way, to specify public/not p. for the collections in multiple collections.
