Here is my Tracker that I coded it around 2010 with a very old tool, i.e., Visual Basic 6.0. It is a primitive version of Mendeley, but there are unique feature that I rely on, particularly active folder concept. I often use it to track the papers and other research-related items. Current features by December 2022:
-Organize the papers automatically with the "active folders" concept -A systematic way to archive hundreds of papers and a cleaner desktop -Group the related articles with search-based "active folders" automatically -Record a meeting and take quick notes -Extract a research webpage based on your keywords -Write chronicles and ideas systematically in order not to forget them -Do it with the minimum number of mouse clicks
