To start the ui is an absolute mess and that hasn't improved in a year! It's unintuitive, oftentimes randomly appears in french and other times is just infuriating (having to refresh preview of a signature drops you from detail view to list view 🤦)

The editor is basic and has quite a few issues, bugs such as place holders showing instead of profile image, drag and drop incorrectly places items, near impossible to adjust padding. Vertical alignment is iffy at best and doesn't work as expected, social icons don't always appear after the first edit.
The plugin for email clients is obtrusive, auto loads at start, pops up at load etc and again french only.

Sure it was free, i may even be tempted to subscribe but not in its current state. It screams "abandoned" or lack of care in the product because obviously bugs still exist after a year. It's certainly not worth and certainly not with it being in french half the time 🤷
