Thanks for the card. It was slightly modified to improve search.
Yes. With the previous version of telegram web one could just click on message to select it for reply. Now it is no longer possible. Version Web Z currently has the same issue.
It is definitly a step back in usability. Before you could click the message timestamp for instant reply, now you have to do it over a context menu and the timestamp is completely unused. Feels like it got missed in the transition.
