Redundant buttons, UI recommendations

Redundant buttons above the Text Box : the "New Chat" button on Desktop mode is already above the chat list . And the "regenerate button" is shown when you hoover on the message. Both are unnecessary or at least would be better an option to hide or be able to select what buttons id want there, or none. (like the menu "more actions" on top.)

Personally I liked more the model selection on the top, because now that is just useless space wasted on top.. plus the space needed for them on the bottom = less space for the chat.. It could be better either all on top or all on bottom…

Also , I am on light mode , but the chat list is still dark..

Maybe more customization options for colors, as well as the chat bubbles on the chat… That would be great ! Thanks!!

Oh also , a new button is needed to clear and delete all messages for the current chat and not save it as a past version.
