Updated message input and attachment process in the Telegram Desktop

The current attachment interface obscures the conversation view and blocks interaction with the messenger. This often causes inconvenience — when typing a message, it’s frequently important to maintain context and see previous messages you’re replying to. Also, when composing a message or a post for a channel, users often need to check other chats or their own drafts, and so on. The new interface doesn’t block messenger functionality, making messaging experience more seamless. Additionally, I suggest bringing text formatting options closer to the user. A quick formatting toolbar could appear immediately after text selection, eliminating the need to right-click and navigate through nested context menus.
