Elaborating my comment to an answer...
Question 1: "Enumerate" uses small portion of the page.
Answer: If you use enumerations in LyX / LaTeX, I guess, it does not matter whether you use a right-to-left or a left-to-right language, the indentation will always be the same amount (of course, on the right side if using right-to-left). LaTeX (which is generated by LyX) uses typesetting rules that are quite professional. You will also see that an average line (at least in English) has about 65 characters and thus, a quite big margin might be left. This limit on the length of a line is used for better readability. Here is an example.
The example was simply created by using a new LyX document with
\usepackage[english]{babel}
\usepackage{blindtext}
put into "Document > Settings... > LaTeX Preamble" and
\blindtext \blindlistlist[2]{enumerate}[2] \blindtext
put as TeX code/ERT (<Crtl>-L
) in the main document. (Note that the LaTeX package blindtext
is used.)
Question 1a: How to replace this numbering with Hebrew letters.
Answer: As a quick workaround you can use the description environment instead. Then you should be able to put any label you want. (Furthermore, nesting of enumerations, itemizations, descriptions is possible in LyX.)
Otherwise see Robust method to apply Hebrew numeral in an enumeration list? (Possibly you need ask a separate question how to integrate that in LyX...)
Question 2: Long equations are divided incorrectly...
Answer: LaTeX break equations not at arbitrary points but usually after relation symbols. If you do not like the break up then - as a workaround - you can split the inline math environment into two or more.
You might also search on this site for questions tagged with math-mode and line-breaking.
Question 3: The equation is cut in "Display Mode".
Answer: A common way to deal with long formulas and many equations is to use "Insert > Math > AMS align Environment". Then you can add rows and break up the equations over several lines. It looks like in the following picture.
Having two AtBeginDocument
commands seems unnecessary (and maybe problematic). Having the following in LyX's LaTeX preamble worked for me:
\newlength{\abc}
\settowidth{\abc}{\space}
\AtBeginDocument{%
\renewcommand{\ref}[1]{\mbox{\autoref{#1}}}
\renewcommand{\equationautorefname}{\hspace{-\abc}}
\renewcommand{\sectionautorefname}{sec.\negthinspace}
\renewcommand{\subsectionautorefname}{sec.\negthinspace}
\renewcommand{\subsubsectionautorefname}{sec.\negthinspace}
\renewcommand{\figureautorefname}{Fig.\negthinspace}
\renewcommand{\tableautorefname}{Tab.\negthinspace}
}

Since LyX is attempting to show something that represents the output and not the raw LaTeX input, there isn't a way (that I'm aware of) to put extra spaces in the editor since that would imply having them in the output.
One thing you can do as a "dummy marker" is to insert an "ERT" box (Ctrl+L or Alt+I+X) on the line you want to preserve as empty. The ERT box is copied verbatim into the LaTeX source, so if you leave it empty, it will have no effect on the final document.
Alternatively, you could set the document to use vertical space to separate paragraphs rather than indents (Document > Settings > Text layout). Note that this will change your output as well as the LyX representation, but it's easy to change back when you're ready to export your finished document.
