Remove the "vote of confidence" or "vote of no confidence".
In this age of coalitions, this has become a nuisance.
The majority party is always under the threat of this vote of no confidence.
Once a party is elected to form the government, it should never be removed from power using this vote of no confidence. It should be allowed to work peacefully for five years.
The majority party should not be made to suffer due to the whims and fancies of small parties with small number of seats.
Only in extremely rare cases, if the government is really horrible, then it may be impeached on specific and clear grounds.
