Research paper organization

I have a directory full of research papers I have read or want to read. They are all named [last name of primary author][year][first word in title].{pdf,bib} (there is a PDF and [BibTeX] file for each publication). This works quite well, as this is the same naming schema that [Google Scholar][scholar] uses in their BibTeX citations. I want to expand this, though. Some time ago I starting writing a simple GUI application to list these files with their metadata (using [Electron] and [bibtex-parser]), but I never quite got it to a state where I actually wanted to use it. One of my goals with this is to keep all the metadata in a plain text format right beside the files, and not in some database in a third-party application. Any (pseudo-)academic thing I write, I try to write in Markdown and use [pandoc] to make nice printables PDFs (via TeX, of course). [pandoc-citeproc] can read bibliographic references from YAML or BibTeX files, with quite a few metadata fields (see [CSL types][csl]). Ideally, I can just use a simple text file listing some file names and easily build an bibliography that pandoc can understand.
