Keys and tips
Ctrl Z undo, Ctrl Shift Z redo, Ctrl S download, Ctrl D copy the picked text layer, Delete removes it. Arrow keys move it (with Shift: further).
Up to 10 text layers, each with its own look. "Cut to the text" saves just the text with a small border; turn it off to keep the whole picture size, with the text where you placed it.
Your own font stays on your device and is gone when you close the page. Check that its license lets you use it in your project.
