JUDLEX lives on the practice's own computer, and that computer is often a laptop that goes out to a hearing and comes back. You can now put a lock on it: JUDLEX asks for a passphrase when it opens, and checks it on the machine itself, so it keeps asking when there is no network. Inside a case file you can also gather documents into folders and see them together, which changes neither their numbering nor the index you export.
The lock is checked on the computer itself
You switch the lock on from your profile, and from then on JUDLEX asks for the passphrase every time it opens on that computer. JUDLEX checks that passphrase inside the machine itself, so the lock works the same on a train with no signal. It protects the way into JUDLEX; it does not encrypt the files.
Folders in each list
Once a case file has grown, you read it better in blocks: the contracts on one side, the correspondence on the other. You pick the documents that belong together and put them in a folder, and each list keeps its own, some for the originals and some for the classified documents. Grouping changes nothing you will later cite: not the number each document carries, not its page, not the index you export.
Long lists
The lists of a practice grow on their own: clients, case files, facts, documents. Those tables take very long lists without the screen suffering for it, and you run down a case file holding hundreds of documents the way you run down one holding ten.
