2. Where are they on the app and how can I use them?Dear Creator, An extraordinary talent you guys/girls have for making such an amazing app,, seriously loving it,,, still I would like to say a few things which can make it more better than before if u please then please do update 1) I can't rotate my phone,, its only one sided 2) while saving any file there can be no space entered in between them.

3. I paid for the full version to activate the desktop code, but cannot see the code to access the desktop version.I have unlocked everything and the app is just crashed and unusable.
