I't's being a while since I posted but these are my new suggestions and feedbacks:
1. Feature Request Forum for WP User Frontend Pro: So we avoid bloating this one
2. Field Maxlength: Currently all the fields allows as many characters as the user want, so is quite impossible to add the maxlength=”” to any field without using jQuery. Wondering if it would be possible to add this feature in the future? It's quite useful for the username, nickname and even bio fields.
1. Thanks for the suggestion, we are considering it.
2. Actually I wanted to it also and tried it add max length support for every field. But the conflict occurred using with rich text field (TinyMCE). That was real hard make it fit. It's not like you can't, but it's a problem when dealing with a dynamic form builder like this. I am not going into more technical explanations, but the TinyMCE is the only reason that stopped me to add that feature. I'll try to sort it again 🙂
