I'm using this app a lot, it's a great prototyping tool, and a good alternative to just use shadertoy in a browser.
There's a couple of features missing, though, and a few usability rough edges:
- no support for float or half textures/render target; this is super important for GPGPU that is not just instagram-like filters and something that would be needed in order to be actually compatible with shadertoy.
- if you have a lot of passes, you can't currently reorder them (or at least I did not find how) and have to resort to workarounds that make everything less understandable
- can you even search/replace in your code?
- going forth and back to/from other editors, it's super annoying that this seems to be the only one not supporting scrolling by just dragging the text - you have to find the small trackbar on the side, which is way to close to KodeLife separator when multitasking on iPad pro
- when working on a file for some time, if you save multiple times, sometimes the original filename is lost and replaced with the default :you have to specify the file name again and override it, and if you have a lot of them it is super error-prone
I still think this is a great app, but it could be perfect with a some ironing :)
