Is your proposal related to a problem?

Importing settings overwrites my existing settings. For example if I have some saved posts in an account and some others in another they get overwritten.

Describe the solution you'd like.

I want to merge settings for example have all saved posts or followed communities from both accounts in the one I'm importing into, without overwriting the existing data.

Describe alternatives you've considered.

I haven't considered any.

The import doesnt remove any existing saved posts, it only adds new ones. Same for followed communities just above. Did you test this properly?

[8ullyMaguire]

I guess I didn't, my bad.

seems like you can't import just a list of communities though

I was looking at this post https://feddit.uk/post/11434169

decided to build a little Javascript:

var links = document.querySelectorAll('#postContent a');
var coms = [];
links.forEach((i) => {
	var m = i.text.match(/!(.+)@(.+)/);
	if(m) {
		var c = 'https://' + m[2] + '/c/' + m[1];
		if(!coms.includes(c)) {
			coms.push(c);
		}
	}
});

var json = JSON.stringify( { "followed_communities": coms }, null, 2 );
console.log(json);

got this JSON:

{
  "followed_communities": [
    "https://lemmy.world/c/star_wars",
    "https://lemmy.world/c/starwars",
    "https://lemmy.ml/c/starwars",

and I got this error when trying to import:

{"error":"unknown","message":"There are no changes to save. This query cannot be built"}
