+# TODO List
+
+Not in any particular order yet
+
+### Big Items
+
+##### Alternate Locations
+
+This helps peers discover new sources for a file while the download is in progress.  Also makes sharing of partial files possible.
+
+##### Bloom Filters
+
+This reduces query traffic by not sending last hop queries to peers that definitely do not have the file
+
+##### Two-tier Topology
+
+This helps with scalability
+
+##### Trust List Sharing
+
+For helping users make better decisions whom to trust
+
+##### Content Control Panel
+
+To allow every user to not route queries for content they do not like.  This is mostly GUI work, the backend part is simple
+
+##### Packaging With JRE, Embedded Router
+
+For ease of deployment for new users, and so that users do not need to run a separate I2P router
+
+##### Web UI, REST Interface, etc.
+
+Basically any non-gui non-cli user interface
+
+### Small Items
+
+* Detect if router is dead and show warning or exit
+* Wrapper of some kind for in-place upgrades
+* Download file sequentially
+* Unsharing of files
+* Multiple-selection download, Ctrl-A
+* Automatic sharing of new files in shared directories (more like medium item)
