Since my GPS logger is so bad that it can't report height accurately, it would be great if there would be a filter that adds height for each xy point instead of recorded height.
Yes, it's definitely possible, and it's on the list. I haven't had much time to work on the site lately though, so I can't say when it's likely to get done.
If you (or anyone else) can help with some research into it, it would help it move along faster, e.g. where to get the altitude data (as a free online service or data download).

Maybe this could be useful? BTW; your site is great, please don't turn it of. I don't have a sense of how many people uses it, but I hope many :)
