I would suggest use RALEE—RNALignment Editor in Emacs. It can get for you the consensus secondary structure, you can move left/right sequences and their secondary structures (you can't do it in JalView!), and more.
It's an Emacs mode, so could be a bit hard to start off, but just try, you don't have to use all Emacs features to edit your alignments!
The RALEE (RNA ALignment Editor in Emacs) tool provides a simple environment for RNA multiple sequence alignment editing, including structure-specific colour schemes, utilizing helper applications for structure prediction and many more conventional editing functions.
