I don't understand what you want..
*.* is the same as "" (empty)
nope
empty mean if you write coolprogram in view filter
its will find super
coolprogram and
coolprogramawesome and super
coolprogramawesome
and if im only add to default filter view *.*
its will become *.*coolprogram
and it dont will find anything
about ctrl+f im quote yourself
but here already too much buttons and hotkeysxD
and im used already ctrl+f for global search
im know im can change hotkey but then again
but here already too much buttons and hotkeysxD
