Ela S. Well developed information manager from Germany:
MemoMaster allows administering and collecting information of texts, pictures, and calculations of any kind. Memos are created and structured in folders, sub-foldersand tabs in form of the proven tree structure.
MemoMaster administers descriptions, non-fictional texts, useful directions, protocols, model texts, verdicts, addresses, text blocks, pictures, recipes, tables, forms, links and files. These texts are saved structured and become available for several users.
The integrated full-text search function allows to perform targeted research; whereas every entry can be retrieved easily. Memos and folders can be moved, sorted, highlighted within the tree structure or be tagged with icons.
MemoMaster also imports texts from PDF files or creates PDF documents - if desired including password and access protection.
Pls read more on their website. It's a nice and stable program with an active developer team.
