+A Java UI which counts word occurrences in a text file. Results are sorted in alphabetical order and saved in a simple HTML file. With this, you can:
+* Search for multiple terms at once.
+* Quickly find misspelt words in large texts
+* Sneak into the context around some keywords.
 
 ## How it works
 Numbers and bracketed numbers (often reference signs) are listed separately.

 With regular expressions, simple filtering for data types similar to ISBN, date or time, URLs or e-mail addresses is done; these tokens are listed separately as well. As regular expressions can be fiddly, I focused on a simple and stable solution so this filtering may not always yield perfect results.
 
 ## Use cases
-* Find out which ISBNs, e-mail addresses or URLs occurred in a long e-mail or messenger thread.
-* Have all occurrences of a word or a name been spelt in the same manner
-* Does a text contain a specific search term, at which line number and in which context, that is, within which sentence or paragraph, does the search term appear? The size of the text around that search term can be specified by the user.

 ## Usage
 `Open File`: browse to a text file. Set the topic (this will be the HTML title) and the target filename. The ending `.html` will be added automatically if missing. Target file will be placed in the same folder as the source text file (folder choice button may be implemented later).
