GOG wallet is a great budget management tool that allows to better control one's spending. I personally use it a lot. Please make it so that you are able to easily see how much funds you have and add funds via the Galaxy client. It is really annoying to go to the website every time you want to check your balance or add funds. Steam wallet, for example, is very well implemented. Firstly, you can always see your balance next to your name and profile picture. Secondly, you can easily add funds through the client.

Sorry for my English. I hope it's at least somewhat understandable.

I agree! Upgraded to Galaxy 2 a couple of hours ago and I find it complicated to view my wallet funds. :( I needed to select some random game, add it to the shopping cart in order view my funds. Why not keep this feature where it belongs? In the dropdown menu beneath our username icon, right next to Account Management and Orders History?

If you want customers to give you money, why bury this feature and make it difficult to access? Frustrating. :(

I also would like to see an easy access wallet button in the GoG Galaxy Client 2
