🎯1.add an option to add custom font files ("ttf") like we can in notein. 2. add double tap Undo gesture for onePlus pad Stylo.( samsung isn't the only brand in the market) 3. add a feature to backup stickers like notein. 4. add a Free Scrolling option like notein. 5.any photo, text, sticker should be placed in such a way that they are partially in the frame and left-part out of the frame. (positioning shouldn't be bounded in the canvas only)

I was just doing something and couldn't add a new page, so I closed it. now everytime I try to open it, it wants to sync a device (one or none show up), but it always goes back to no connection to the wifi - what isn't true. I logged out multiple times, deleted the app, logged back in. tried even to log in with my phone, to see if it was just a problem on my tablet. nope. there's no new update too. fix that problem please, I'm serious

Overall experience is very good.. I came across this app and purchase it. Kindly make the pop up document as it pops up in previous version rather than cover it up the whole bottom space horizontally. It is very annoying for me. I love that feature. Second make the pen menu customizable like we can rearrange the pens according to our convenient rather than in the order of their creation. Happy to hear from you.. Thanks.
