I oppose.
Sorry, I believe in separation of powers. The fact that governors can general propose legilsations in Region Assembly, I'm not opposed because regions aren't always ultra active and sometimes it can be a one man show (althought right now all regions are deeply active and I'm really happy with that), but for the senate, we have 10 senators that are willing to introduce any legislation Lumine would want to be introduced. So I don't see the need for this reform.
How would this harm the separation of powers, considering that one of the two objectives here is to merely legalize something that has been done for the past months? The process may be faster if the executive (President + VP, I certainly support that idea) can indeed post in the thread, but he is not taking any powers away from the Senate given that he still requires a sponsor.
Furthermore, and going to the second part (the extra executive slot) the queue can often find itself filled with bills (often coming from one or two Senators), which means that a crucial piece of legislation for a national emergency could get stuck for too long. Considering that most of the nation believes that the President has to be involved with the Senate, and that we often have more than one crisis or major issue at a time, wouldn't it make sense to allow for two emergency slots for the executive as well?
