[[Brainstorming version 1.0 (old)]]

h2. Current version

h3. 1.1

See "here":http://dev.d-lan.net/versions/21

h2. Future versions

h3. 1.2

See "here":http://dev.d-lan.net/versions/25

h3. 1.3 

* Add a stats tab with some graphs :

** A graph of download and upload rate over time

** A graph of the number of peer over time

** A graph of the sum of available global data over time

** A graph of the total download and upload rate over time

** Stats are persisted in a file

** Data can be exported in csv files

** The most uploaded files (this day, this week, total)

** The total bytes uploaded and downloaded (this day, this week, total)

* Add an option to be able to move and re-size windows in the MDI area.

* Be able to drag'n drop a file or a folder from a remote peer (browse window) to our local folders (local browse window).

h3. 1.4

* Handle URL (link) in the chat and the log

** An URL is displayed on top of the file browsing windows like : _D-LAN://192.168.1.46/movies/sci-fi_. It's allowed to copy or paste an URL.

** Add a link definition. The user can make link from its files/folder or from a remote file/folder. See [[Protocols#Links-to-resource]].

** To develop...

h3. Not planned

* The user can set a flag to active bandwidth and CPU limitation. If activated then downloading, uploading and hashing rates will be reduced.

** This option is available from the trayicon (Core) or in the settings panel (GUI)

** Automatically detect a running game and set the limitation flag.

** Automatically detect CPU/bandwidth usage and set limitation flag.

** See by an icon next to the peer name in the peer list when a peer has setted the option to reduced the bandwidth.

* The user can dynamically change the number of _downloader_ in the settings window (1 to 10 for example).

** More downloader will increase the global transfer rate but will download more file in the same time thus the files will be available later.

* Detect duplicates (files which have the same size, same hash and same name) on the local machine and allow the user to easily remove them. 

** [Greg] Compare only the hashes is better because some identical files may have not the same filename. Moreover the size (or the name) is pointless because the hash identify the data.

** There is a button somewhere to open a blank browsing window.

* The users can add some comments or tags associated to theirs sharing. These comments or tags are displayed in the list of peers (new column ? tooltip ?).

** You can switch the peer-list to a tag-list

* Virtual folder to aggregate some real folders. For example the virtual folder 'Divx' may merge '/mnt/Divx1', '/mnt/Divx2' and '/home/paul/movies'.

* Protect some sharing by a password / user rights for shares.

* IPv6 support.

* The user can save favorites (a folder in a peer). The favorites are displayed in a panel below the peer list.

* The peer list shows by an icon the OS (Linux/MacOSX/Windows)

* Identify certain file (like mp3) without theirs metatags. Same mp3s with different id3tag will be considering to have the same content.

* The user can create peer groups and drags peer into like a classic IM (pidgin).

* Automatic update system under windows and mac osx. Like Firefox.

* Try to keep a small core and add a plugin system like Firefox.

** Use of qt-script for plugins ?

* To have the Windows 7 compatible certification : http://www.readyset7.com/software.aspx :F

* Using of "Lucene":http://lucene.apache.org/ for a better searching engine

* Create a voting system per peer, you can tell if you like or dislike a peer ('+' or '-'). Then, a good or bad icon will appear next to the nick of each peer in the peer list. If a peer share virus or corrupted files it will be shown as such.

* Use "THEX":http://open-content.net/specs/draft-jchapweske-thex-02.html#anchor4 to verify file integrity.

* Ability to ban a peer, for example leecher.

* Use of the "Tonika":http://pdos.csail.mit.edu/~petar/5ttt.org/ network to be able to use Internet to exchange files.

h3. Technical

* Use of a faster malloc (and optimized for multi-threading) lib like "tcmalloc":http://goog-perftools.sourceforge.net/doc/tcmalloc.html or "jemalloc":http://www.facebook.com/notes/facebook-engineering/scalable-memory-allocation-using-jemalloc/480222803919.

h4. Searching

* User can use quotes to search a complete sentence, for example : "I have a dog".

* Search in meta data like ID3tag and in compressed file (zip, etc.).

h4. Chat

* Private chat (point-to-point).

* Chat by channel (each user can join one or more channel and he will receive all the messages broadcasted to the selected channels). The channel can be created by any user (like battlenet).

* Status : online, occupied, away. (with auto away)

* Be able to mute someone

* Bridge to IRC, each core act as a IRC server. This feature should be implemented after channels and private messages.
