Bug#770377: (no subject)

[Andriy Grytsenko]

25 is not much a difference from current limitation which is 20.
When you tell about 10 - 10 is default, which can be changed in the
configuration dialog, but you cannot increase it over 20, only way to
increase is manually editing ini file but in that case you will be
forever prohibited to open configuration again because it will then
instantly reset it to 20 and drop all the history items over 20.

Just compare it with the URL history which is maxed to 50. Have partial
history being much bigger than full history is insane, and I believe full
history should be allowed to set to 50 as well.
