Just purchased this app. I have two comments -- firstly, why are images restricted to a square format? And secondly, why is the Tool Tip text shown as yellow on pale grey? It's unreadable.
Hey, thanks for purchasing the app. the canvas is limited to sq resolutions to maintain simplicity of the app and it works perfectly with the preset grid sizes. The tooltip issue occurs only when the app is started and it works normally afterwards, this issue is fixed in the next update, which you'll get for free
I feel like this is some sort of shortcut infecting virus on your computer, because it has removed only the shortcut on your desktop (not the app). If you could look into the second notification (which is 7 hours ago) and if it's the same (infecting .lnk shortcuts), you should probably run a full system scan. I would advise you to run a deep scan right now, using bitdefender/ windows defender.
