Vertical height can be more lowered

[ky-jp16]

Hello. I am a Japanese "Orzeszek Timer" user and I tried "Hourglass" this time.
And I found that the only inconvenience point of "Hourglass" was that the vertical height cannot be shorter than a certain length. I want to use "Hourglass" in a small area.
I would be happy if you could address this in the future.
Thank you.
