Currently the session-id is created based on IP, not device. When 2nd device/user under same network calls init, new session-id will be created overriding the 1st device's session-id, resulting in first device unable to call any method as the session-id is no longer valid on server.

Let's say you have 10 products, you create 1 master key in any of these products, which means it is duplicated for the other 9, after the user uses the master key in any of the products, the hwid is applied to all the others too, if you reset the hwid in any product in the panel, it will reset immediately in all and and so on I'm not sure if I explained it correctly and whether this is the best implementation, but the point is very simple: sell a subscription for all 10 products at once, while not sending 10 keys to a person, but only 1 If you have a VPN, ANTI-VIRUS, WINDOWS CLEANER and each piece costs $ 20 per month, then with the Master Key you can add a product for $ 45 per month and the user can use all 3 pieces and it's cheaper for him, but for the seller it means that he sold 3 products at once.

so in our users list how we have view options we can use like "HWID, IP, Creation Date, Last Login Date" i was thinking add one more view option since there's one more empty spot left you can put "Expiry Date" that way its easier for us KeyAuth users to know if our users plans have expired or are getting close to expiring!

The application has a divided functionality, which is available through different subscriptions. I would like to be able to activate multiple subscriptions for the same period of time with one key. He should also renew the user's existing subscriptions and add a new one if there was none.

I would like to implement webhooks via sevrer KeyAuth in a telegram bot, similar to how it is done in Discord.

So I wanted to see cached checkboxes, to mark it one time, for example Lowercase/Uppercase checkboxes when generating license with website, when deleting license there is "Delete user too?" checkbox as well that is not being saved.

So would be really nice if you make so when you upgrade the same subscription you have it won't add to user subscriptions like a new one, just make the expiry later.

please don't make App limit and User/license limit. license is already crossed than 10 thousand. as expired license doesn't get erased and for seeing who has generated key it needs to keep the log. so don't keep that limitation
