Usually, the easiest current way to translate targeted texts, that are most commonly used than others, I have to use the browser's find in page tool in the English lang file to find the string's name, and find that string in the language's string, which includes jumping between the game, English lang tab and the translator's tab.
I would suggest if there is some kind of search tool to search the English texts, I know it wouldn't work for many short strings, but mostly helpful for the longer strings.
I am fine with just searching the English lang file, but this would be a helpful tool if it's possible.
Thanks.
