Can get bigger by adjusting the space of typing a little bit smaller as you're expanding it, it doesn't have to be a big adjust. I just think it's kinda small how it is. Like you can't fully see these small signature pictures without the need to hover over it I mean, there is a big space for typing that's kinda useless because you usually don't need that much of space and if we expand the signature it won't effect it anyways because the space of typing expands depending on how much you type
Text box size wouldn't effect signature size. There is 1 text box and 1-20 signatures per page. Whoever wants to see your signature can hover over it You mean the post size? It shows all the text, yeah. But that still has nothing to do with the signature size.
Expanding the size would make each page 20x whatever size you increase it by because there is up to 20 per page
Because a few people have huge signatures (stacked images and such), so instead of displaying them all you are limited to a certain size but if anyone is interested in seeing the whole signature they can hover over it.
