Duolingo should make more things to do with your lingots.
My lingots are piling up and I want to do something with them.
Use them for lingot giveaways if you have bought everything in the store. I think they are making new things for the stores, but I am not sure. :)
I have roughly 1,200 lingots, thus I do hope they introduce something new... And I still spent approx. 100-150 lingots every months. I just keep the rest in case something really great new awesome fantastic will be introduced to the store ;-)
It would be nice if Duolingo sent you a notification after someone gives you a lingot on a comment telling you where you got them from. I've noticed mine just passed the 200 mark when it was 190 something the other day. So I spent a while going through conversations I've posted on to see which comments people were giving me lingots for. And I have all my notification options turned on too.
You should be able to buy multiple items such as heart refills and streak freezes.
With the heart refills, for example, you could only use one per lesson (so you can't buy your way through a lesson), but they would stack.
Just an idea.
I think this is a great idea, personally. I wouldn't mind buying several heart refills in a row just to know I'd have one on hand when I needed it, and there have been multiple threads started here by people expressing frustration about not being able to set their account to "on vacation" or buy an extended streak freeze when they're on a trip and have limited internet access.
How do you accumulate so many - is it through immersion? I seem to only have about 20-60 at any time.
I get them through finishing lessons and all kinds of other ways, and also I don't use them very much.
Totally, I use them all the time for refills. I'm mostly using Duo via the app, and I'm constantly having issues with auto-correct or typos that make me lose hearts.
That happens to me once in a while on the app; my advice is to activate the foreign language keyboard of relevance to you on your phone and use it for the FL sections to help with autocorrect errors screwing you up. (It's very easy to switch between the two keyboards on iPhone, I assume it's similar on an Android.) My big 'heart' issues generally come from the English to French translations, where I often make grammatical errors. (misplacing a word, forgetting to put an article in place, getting caught between the choice of le/de, that kind of thing.) Ironically, I have less trouble when I'm using my phone because some of these exercises give you all the words you need and let you piece it together (rather than pulling it from thin air), which results in a more constructive/less stressful mindset and gives me a chance to think.
