I thought to add some more description in reference to custom theme functionality.
For the new Android client (v4), I am not asking about any additional functionalities as compared with older client. Previously we had club pieces, neons, vintage and other ones that were accessible via customization mechanism only (the neon theme as such is currently configured only on the web). Neon pieces are colored green in the selection menu but appear red -- it's actually better to have them green but either variant would be very good to have for contrast (glass board with neon pieces is especially strong).
Custom background is another problem -- previous version of Android client had this feature enabled for paying subscribers only. I tried it on non-premium account, the menu wasn't there, I reported multiple times to customer service to no avail (but they acknowledged it was a real bug). The app looks really stunning with overlay board and certain custom images in the background (overlay board is, of course, different from translucent board in very profound ways).
The new client does not appear to store images in the cache folders (e.g. 144.png board files) so there is no way for us to override them manually with our own images.
I got an understanding that both problems described above are ticketed and in scope, so we should expect them to be worked on while the app is in beta phase (please confirm if possible).
I would be happy to provide any additional description to make sure you introduce best correction possible. In a nutshell, I am asking to only introduce all features that were in the previous version, nothing new.
