Add 'Lock' checkbox right after 'mSearchBox' (and before 'Regex' checkbox) in 'SearchListView' class. At interface point of view, it's just a simple checkbox, which locks search textbox if checked. So, the main apply of this option is lay down at implementation POV. At that time it's used only in 'SymbolView' UI, for purpose - now you can search for, for exmaple, 'Nt' functions in one module, check 'Lock' checkbox, and then go through another modules without tedious retyping of the same search query again and again. Simple, but useful. (#1003)
