You can disable canvas rotation in Settings.

I take your point, but I'm not sure it's essential to have both the frame hold panel and the audio panel visible simultaneously. 

I tend to make notes on the canvas, or even go proper old-school and use a separate exposure sheet (with pencil and paper!) to keep track of sound cues, music beats, speech etc.

Everyone's got their own way of doing things, of course, but with an app that's designed to work on phones, there's always going to have to be compromises. 

I think I solved this one! :-)

It seems you have to be careful actually to drag and drop the sound file into the project.  If you click and let go too soon, the sound file does drop into the project, but does not play.

I still don't seem to have the option to share images from the frames viewer to the gallery on my tablet.

Having seen how well the audio menu works - I think it would be fantastic if you could have a similar screen that scrolls up from the bottom, when activated, to control the frame-hold and layers functions.  I made this mock up to show the kind of thing I mean.   The ability to show or hide this part of the UI, as you can with the audio, would make for a great compromise between screen space and functionality.

You can export a PNG sequence with transparent background. It works well, I do it all the time.

I agree, I posted the same idea here:

The onion skin needs either to be toggle-able on a per layer basis or to reflect the opacity setting of the layer so that layers that are being used for tracing do not fill the canvas with unwanted onion skin content.

In the project window, click on the three dots icon on a project to bring up the options. Click on 'Backup project' and choose a location to save to. The backed up project can then be imported into FlipaClip on another device.

I agree. A single finger long-press is a great way to bring up tbe colour sampling tool. It would also be much better if, once the colour was sampled, the app returned straight to the canvas, rather than going to the colour editing dialogue.

I like to make a pallette on a separate layer of all the colours or shades I'll be using, but the current colour sampling method requires four or five clicks to grab a colour. With the long press method, it would be a simple single click each time I needed a new colour.

I have a feeling this behaviour may be related to copy and pasting frames between projects. I was working on a 1280 x 720 project and pasted in some frames from a 1920 x 1080 project.  It all worked fine until I tried to merge some layers, at which point some of the elements jumped to different sizes and positions.
