Hello everybody! Can you help me?

So, i´m a admin of a community and recently we changed for MYBB.... Anda i´ve some doubts about visual things:
I will attach the prints:

1 - on the first, i´d like to make these content parts below the header, more larger ant set the stats mysql loading align center. I think this will resolve a issue on mobile view, that only works in Chrome. Safari, Firefox and Brave, for example, everythink stays far.

2 - I know it´s MYBB default, bus is possible the attachment stay in te top, above the content of post.

3 - Increase the size of quick reply text area, is too small.

Thanks for attention and congratulations for all skins here! They´re beautifful!

Brunno.
