Added some shiny PR to the windows, honestly. It is just at the begining of the manual, so maybe it will raise morale of the user ;-)

 Creating regexps can be a difficult and annoying -- especially when you need complex criteria. On the other hand, We are under impression that in reality complex expressions are needed only in sporadic cases. In fact, the truth is: that most of the time only already mentioned ``.*'' is needed and therefore the following description of regexps can be skipped by vast majority of readers.\\
 
-Before working with Regular Expressions, you should understand what actually are regular expressions. Essentially, the idea is simple: when you are writing any word, you are using strictly defined latters -- that is: latters create a word. What you want to do with regular expression is to use set of rules that will match to many words. It is not that difficult to see what it's needed to do so: first, you will clearly need way to determinate what latters you want to match (word is composed by latters).\\

 Before introducing other ways to choose between characters, I want explain anchors. Anchors allows you to decide where to ``look'' in the string. You surely should know about ``^'' anchor and ``\$''. Putting ``^`` will tell to Open{CS} to look on the beginning of string, while ''\$`` is used to mark the end of it. For instance, pattern ''^Pink.* elephant.\$`` Will match any sentence Beginning with the word ''Pink`` and ending with '' elephant.``. Pink fat elephant. Pink cute elephant. It doe not matter what is in between because ''.*`` is used.\\
 
-You have already seen the power of the simple ``.*''. But what if you want to chose between only two (or more) latters? Well, this is when ``[|]'' comes in handy. If you write something like: ``^[a|k].*'' you are simply telling Open{CS} to filter anything that starts with either ``a'' or ``k''. Using ``^[a|k|l].*'' will work in the same manner, but it will also cover strings starting with ``l''.\\

 And What if you want to match more than just one latter, just use ``(|)`` it is pretty similar to the above, but it is used to fit more than just one character. For instance: ''^(Pink|Green).* (elephant|crocodile).\$`` will be true for all sentences starting with ''Pink`` or ''Green`` and ending with either ''elephant.`` or ''crocodile.``.\\
 
-Regular expressions are not the main topic of this manual. If you wish to learn more on this subject please, read the documentation on Qt regular expressions syntax, or TRE regexp syntax (it is almost like in Qt). Above is just enough to use Open{CS} effectively to be sure.

 \paragraph{Value -- value(``value'', (``open'', ``close''))}
 While string expression covers vast group of columns containing string values, there are in fact columns with just numerical values like ``weight``. To filter those we need a value expression. This one works in similar manner to the string filter: first token name and criteria inside brackets. Clearly, conditions should hold column to test in. However in this case wanted value is specified as a range.\\

You are free to create as many windows as you want to, free to populate it with any widgets you may want to, and move everything as you wish to -- even if it makes no sense at all.

+The principle behind this design decision is easy to see for Bethesda made editor, but maybe not so clear for users who are just about to begin their wonderful journey of modding.\\

+\subsection{Advanced}
+So why? Why this is created in such manner. The answer is frankly simple: because it is effective. When creating a mod, you often have to work only with just one table. For instance you are just balancing weapons damage and other statistics. It makes sense to have all the space for just that one table. More often, you are required to work with two and switch them from time to time. All major graphical environments commonly present in operating systems comes with switcher feature, that is a key shortcut to change active window. It is very effective and fast when you have only two windows, each holding only one table. Sometimes you have to work with two at the time, and with one from time to time. Here, you can have one window holding two table widgets, and second holding just one.\\
