[Feature request] New due-date time entry is slow

Is your feature request related to a problem? Please describe.

The new time entry which came in version 0.17 is in my opinion an usability regression.
When creating a new tasks, before I could set time by clicking on pulldown, scrolling to time I wanted using mouse wheel and clicking again. This was far from ideal, but significantly better than current state.
When I want to schedule task for 12:00, I need to click once to display the new GUI and then 12 times to get to 12:00. It would be even worse if I wanted to select 12:30.

Describe the solution you'd like

Previous version was better, because the current one is just slow.
What would improve things significantly would be if the new GUI reacted to wheel scrolling, which would make it much faster.
But the best and fastest way is in my honest opinion how Google calendar does it. If I want to schedule something for 12:30, I just type 1230. This is super fast and comfortable. I believe this can be added easily to the existing solution.
Current solution allows for typing the time, which I use often and frankly is the only viable way in 0.17 for me, but the problem is that I MUST type the ":". That makes it significantly slower and annoying.

Describe alternatives you've considered

Described above.

Additional context

No response

No file or test is named. Start by locating the due-date time-entry UI and checking how its current input handles separators and scrolling. Done means users can enter times such as 1230 without typing a colon, with the resulting due time preserved correctly; wheel scrolling is an additional requested improvement.
