Hey!
These are very good bugs, lemme go at em one at a time
1. This one's weird... Maybe the audio script isn't keeping up with the actual read out script...? maybe the indexes are getting mixed up? I'll give it a look tomorrow, it's gotta be some weird timing oversight in the Read function. I changed some code there recently, so I might have broken something.
2. I probably have some field labeled incorrectly, or it's not refreshing the inspector like it should? For now, create in assets folder, click "ping" while your assets folder is up to go to the autoclips, and duplicate one by hand. Click "refresh database" in the STM inspector to update it.
3. THAT'S!!! a really good idea! this should probably be the default behaviour, but I wouldn't be able to have it be animated when it scrolls up like that. I'll try to figure out how to add this to the Read function, cause it really should do this. It might also be possible for me to do w/ vertex modification, since I can use that to change what vertices are visible as a mesh is being read out. For now, I could try modifying the shader to use the stencil buffer, or try the included UI Masked shader and see if that works? It's an old shader, and sorta hacky so it might not work.
I dont think the value for the current line being shown is an exposed one, but I could be wrong? It'd be somewhere int he code near the "lineCountLimit" variable, since those need to interact. The current y position of a letter might also be useful for this?
4. If I were to add a tag that let you set an additional offset for text, would that work? Something like... <o=-1> to offset the next letter by 1 unit to the left? For now, try making a quad (Inline image) to use as a bullet point since you can set an offset for those already. That's the best quickfix I can think of. I think and indent function could be done tho, I'd just have to have the mesh remember the offset, and start new rows from there... I think it'll be doable, so I'll probably add that!
It's already pretty late here, so I'll look into this more tomorrow! Some of these things I typed are also notes to myself, so sorry this response is a little free-form!
