Title: Bring Reaction Menu closer to the message text on wide screens
Description:
Currently, the hover reaction menu is always pinned to the far right edge of the message container. On ultra-wide monitors or when using the "Full width" display setting, this creates a huge physical distance between the short message text (on the left) and the reaction buttons (on the far right).
This is exhausting for the user's eyes and requires excessive mouse movement for every single reaction.
Suggested Solution:

Allow the reaction menu to float near the end of the message text if the message is short.
Or, add an option to display the reaction menu on the left side of the message.
Or, trigger the reaction menu via a right-click at the cursor's position.

This change would significantly improve the user experience for everyone using high-resolution displays.
