Total Commander

First, it doesn't remember when I use "search substring" option.
Second, "search substring" activated by additional checkbox - why?? It's more than enough just to check "search string" - if it's empty - no text search needed.

Hm, that sounds logical to remove checkbox at all... Interesting why it has been added...

Any chances that the suggested change of removing the "Find text" checkbox in "Find Files" dialog will be implement?

No, this isn't planned. Why: If you want to repeat a search with the same search text, you can do it now with one click because the name is pre-loaded. If there is no checkbox, I cannot preload the previous string. Then users will have to use the text search history (2 clicks).
