(Simplified) lock ability for better touchscreen experience

I have a business and a personal Coda subscription, the later is only a Pro tier, so it misses the ability to lock documents, which would be a great help for way better touchscreen experience.

I like building webapps for iPad, but I have to be very careful using them, since a single unintended swipe would mess up the whole layout that can only be undone with the attached keyboard folio. Also, Safari keeps bringing up the onscreen keyboard even if I push buttons only.

My idea is a simplified lock mode, that is interact only, restricted to buttons and scales.

(and no permission management is needed from Team tier, of course)

A simplified lock for the Pro subscription would be great. I always change the layout of a page by mistake. For example, if you click anywhere outside a button or a table, coda automatically inserts a new paragraph, which changes your whole layout.

I can understand that all the detailed locking features are made for enterprise teams and it makes totally sense for me to charge for that, but for a personal Coda user like myself, upgrading to the Team subscription and paying 36$/month is a lot of money. Therefore having a simplified locking ability for the Pro subscription would be awesome.
