As a landscape photographer, it would be nice to use my iPad for traveling and editing, but without these fundamentalediting options, I am still forced to take my laptop with me. And before anyone says "but you can do HDR merges if you take the photo with your device," let's keep in mind that Adobe is supposed to make professional products. I am not using my phone to take professional images.
I don't know how you, as professional developers, can release the Lightroom app without HDR and Panorama.

I second 'selondon's' advice about posting your enhancement request. I would also love to see pano-merge and HDR-merge in the mobile app!
However, I also want to make it clear that the camera inside the Lightroom app does capture HDR image. What it does not do is HDR merge from images in your catalog, and it does not let you save out the bracket images used to render the final HDR output from the LR camera. If you enable "Save unprocessed original" in the in-camera options, then LR does save both the HDR and normal expsoure DNG image for each shot captured.
