I present to you a Jevix snippet for filtering and typing content on the site. Habrovchane are well acquainted with her, because she comes from here: 
0.9 beta , 
0.9.5 , and 
1.0 .

My snippet doesn’t bring anything new, just now MODX users can install and configure Jevix on their site with a couple of clicks.
All parameters are flexibly configured, errors are written to the system log. There is a description of the parameters in Russian (copy-paste from class methods) and English (my clumsy translation).
It's easy to call:
[[Jevix? &input=`[[*some_placeholder]]` ]] 
Parameters can be changed with each call:
 [[Jevix? &input=`[[*content]]` &cfgAllowTags=`b,a,img` ]] 
You can send to the input any placeholder or text.
This is the first version, for sure there will be errors - so, be patient.
