 # Fixes
 
-- Better addressbook column widths
-    <zzz> on the i2ptunnel and addressbook pages on the tablet, the columns are too skinny, they aren't as wide as the tab
-    <zzz> only a few addressbook entries wrap but on i2ptunnel everything is wrapped and most of the screen is empty
+- Create tunnel wizard
+    <zzz> hmm would be nice if they could be shared-client or have an option
+    <zzz> was setting up email tunnels
+- Browser
+    <zzzccc> Bug report: i2p browser treats 302 as an error
+    <zzzccc> Bug 2: rotate screen in i2p browser seems to go back one page
+- Console text change
+    <zzz> "download" and "upload" at the bottom of the status is a little misleading..
+    <zzz> maybe 'downstream bandwidth' or 'inbound usage' ?
+- Fix visibility of advanced tunnel parameter changes
+    <zzz> when I change an advanced tunnel param e.g. length or variance, the change isn't displayed, I have to go back and forward again to see the change
+
+# New UI fixes
+
+- Addressbook action items are in tunnel overflow menu after moving from console to tunnels
+- Material design:
+  - Style for addressbook headers
+  - Change console FAM icon when possible
+    <zzz> on the bottom right, the + and x icons might be better as a double-up arrow and double-down arrow?
 
 # Short-term
 
 - Disable uPnP when on cell networks
     <zzz> spewing UPnP out into cell networks is a waste of time at best and a security risk at worst, but you really want it for wifi
+- I2PTunnel
+  - Improve tunnel list status indicators
+  - Show all messages somewhere
+  - Icons/header images for tunnel types on details page
+- Progress feedback for addressbook subscriptions reload
 - Display release notes directly on new router version
-- Text content

-  - Rewrite release notes to be release-specific
-  - Fill out help page
+- Fill out help pages

   - Create nav history when viewing RI from LS
 - Include GeoIP db for country info
 - Maybe change router-off mechanic for various pages? Enable as they become available?
-- Add "copy (error) log" option
 
 # Medium-term
 
+- Network profiles
+  - User selects profile in settings
+  - Change network participation etc. based on profile
+  - Also look at connection type: Connectivity.isConnectionFast()
 - Expose log level overrides
 - Improve graphs
-  - Show time on bottom axis
   - Show fixed x range, not only available data
   - Think about pan/zoom
   - How to persist data across restarts?

+- Known Vulnerabilities
+  - Apps will be tested to ensure that they are not susceptible to known
+    publicly disclosed vulnerabilities. For example:
+    - Heartbleed
+    - Poodle
+    - MasterKey
+    - Common Path Traversal attacks
+    - Common SQL Injection attacks
+- Network Security Protocols
+  - All Apps that require transmission of data from the App to a system that
+    does not exist on the device must use, at a minimum, TLS1.1 standards.
+    However, Blackphone would prefer the usage of TLS1.2.
+  - Apps must not use algorithms for cryptographic purposes that are considered
+    obsolete or outdated i.e. MD5, SHA1, RC4, DES, or any encryption algorithm
+    that is weaker than AES128.
+- Transport Layer Protection
+  - All network communication should be encrypted
+  - Not vulnerable to SSl Strip
+- Data Leakage
+  - No storage of sensitive data outside of application sandbox
+  - Files should not be created with MODE_WORLD_READABLE or MODE_WORLD_WRITABLE
+  - Copy & Paste will be evaluated on a case by case basis
+  - App logs should not contain sensitive information
+- Authentication and Authorization
+  - Validate that authentication credentials are not stored on the device
+  - Must use an approved password-based key derivation function ie. PBKDF2, scrypt
+- Data-at-rest Encryption
+  - Must use at a minimum AES128 with modes CCM or GCM
+  - Should not store the encryption key on the file system
+- Permission Checks
+  - The App must function with all permissions disabled
+  - Apps must not hard crash if a permission is disabled
+  - Apps should ask users to enable permissions that are disabled if needed to
+    function properly and explain why the permission is necessary
+- Privacy Policy
+  - Apps must have a privacy policy that details how customer data is used,
+    stored, shared, etc...
+  - Apps must be configured with the customer opted out by default
+  - App logs should not contain PII
+- Error Handling
+  - Apps should follow best-practices for error handling and logging
