Latex-encoded diacrytics and year sections

Dear Author,

first, thanks for a nice plugin. I have two questions:
1) In my bib files I use latex-escaped diacrytics (e.g. “author = {Wojciech Ja\’skowski},” in http://www.cs.put.poznan.pl/wjaskowski/bib/wjaskowski.bib). But they are displayed in the site in the original form (http://www.cs.put.poznan.pl/wjaskowski/publications), whereas on the “bibtex” entry page the letters are “converted” (e.g. http://www.cs.put.poznan.pl/wjaskowski/archives/wp-publications/jaskowski11algorithms). I would like it the other way round: the bibtex entry should have the original escaped letter and the reference on the main site should be “converted”. Is that possible?

2) I would like a year-sectioned bibliography like this one http://www.monperrus.net/martin/bibtexbrowser/bibtexbrowser-screenshot.png, so that there are numbers and publications are grouped by the year. I tried to mimic this on http://www.cs.put.poznan.pl/wjaskowski/publications by putting:

2013
[wp-publications bib="wjaskowski.bib" all=true year=2013]
2012
[wp-publications bib="wjaskowski.bib" all=true year=2012]

but the numbers start from begging each section, obviously.

In a case this is currently impossible, may I ask you for a hint where to start modifying the plugin? Any tips would be appreciated 🙂
