Bubble designer / multi line textareas / more advanced features in bubble display

In Nintex RPA the current design options for bubbles are very limited. Other software vendors offer some kind of forms designer to place form fields according to the users needs. Also colors/font faces/images can't be chosen as one likes.

What is really limiting us is that for example there a no multi-line input fields (no textarea available), and option fields cannot be placed horizontal. Like having a o Yes o No Option always results in

o Yes

o No

Even though there is enough space to "place them correctly".

What would be really nice is if there were some kind of forms-designer or to make it possible (maybe by using html or so) to design your own bubbles.

Also can you please take a look at the accessibility of the bubbles? Font-size doesn't scale correctly, high contrast mode isn't supported, tab sequence is irritating, accessibility keys for buttons are very limited ...

thank you!
