Made this in a couple of days starting with no knowledge at all, getting snippets of code for things I needed and modifying them. I'm pretty satisfied with the result and learned a bunch of things during the process.
I need help with two things tho. First: how do I set up the custom search engine with the -wk? I've searched around but found nothing, tried to copy from the start pages from the op but it doesn't work. Is it possible in the first place to do such a thing? The site it should search from is
https://pathofexile.gamepedia.com/Path_of_Exile_Wiki.
Second: is there a way to make so that the notes taken in the textarea are saved, trough cookies or something,so that they don't get lost when refreshing the page?
If anyone wants to laugh at my code, optimize it or use it, feel free to do so, all the images are hosted online and everything is in one file
