2- regarding the forms i already use user pro paid plugin
is there any way to use it instead the default forms used in lifter lms ?
how can i customize the lifter fields and add additional field…and also in arabic website it is still left to right not right to left direction
3-i set all sittings and download stmp plugin and i sent test email it is working
but no notification recived after registration or achivments
how to solve this problem?

is there any way to customize the the method of view lessons to be down each other instead of the current methos in screen shot?

my client ask me to make all lesson Under each other in this section
this type of view is inconvenient for them
