In Spanish we call a 'cajón de sastre' a space to place different kinds of things. This is my Tailor's drawer!

Fitting Tables and Imagines into a Page / Slide
If you've ever had trouble fitting tables, etc. in Lyx, try this trick (from http://wiki.lyx.org/LyX/Figures):
Add \usepackage{adjustbox} to the document's preamble
Change the paragraph layout to the default (Justified).
Add in LaTeX mode \begin{adjustbox}{center} before the image/box/etc., and \end{adjustbox} after it.
If that didn't work for you, try this alternative (from http://wiki.lyx.org/LyX/Tables):
Add \usepackage{graphicx} to the document's preamble
Put the table in a \resizebox in ERT with the syntax
\resizebox{width}{height}{argument}
where argument is in this case the table and width and height can be specified using any of the usual parameters like cm, em, pt and so on.
If you want to keep the aspect ratio of your table, you can set ! as the height parameter,
\resizebox{\textwidth}{!}{argument}
Since the table (the argument) needs to be enclosed in braces {}, you need to enclose your table in two ERT commands. Put
\resizebox{width}{height}{
before the table in ERT and the closing brace
}
after it.
Finally, a solution for images: (from http://wiki.lyx.org/LyX/Figures):
Change the paragraph layout to the default (Justified).
Add in LaTeX mode \centerline{ before the image, and } after it.
Omitting a Slide Number on the Title Slide in LyX (using Beamer)
If you'd like your title slide to be unnumbered, add this to your Latex preamble (from http://tex.stackexchange.com/questions/30461/beamer-nonumber-equivalent-for-slides and http://tex.stackexchange.com/questions/18828/how-to-remove-footline-on-the-title-page-of-beamer-slides):
\renewcommand\makebeamertitle{
{ \setbeamertemplate{footline}{}
\begin{frame}[noframenumbering]
\titlepage
\end{frame}
}
}
This redefines the custom command \makebeamertitle that LyX automatically creates to produce the title slide. As you can see, it produces a title slide without a footline, and sets the slide counter to 0, so that your first slide with content will be numbered 1. You can customize \setbeamertemplate{footline}{} if you display other information (such as author, title, institution, etc.) according to your preferences.
