doing an inline frameless shower door about 58" wide with 1/2" glass. Will consist of one fixed panel and the door. Door will be hinged on the wall and be about 28-30" and NOT go all the way to teh ceiling. The panel will be the remaining width and will be hooked with clips. Was trying to decid on 3 options for panel. 1) have it go all the way to ceiling and attached at floor and ceiling. 2) have it same height as shower door and only attached with clips at side and floor and use support bar off teh top. 3) 2) have it same height as shower door and only attached with clips at side and floor. So my qustions are: How much wobble in #3 and is this unsafe? How bad does #1 or #2 look?

Thanks!
