Option to display history in reverse order

[mhtvsSFrpHdE]

Now the latest recorded history is displayed at top left corner -- farthest location if you want to click on it.

If one often work with 3 ~ 7 history, but set history number to 92 in case don't want to lose any information

Fetch recent 3 ~ 7 is nightmare.

I actually coded that feature myself. But certainly it needs some test to prove stable.
Later will submit a pull request for that.

Update:
For anyone can't wait to get this feature, I have Windows 64 bit EXE for download:
