This is just a dump of some interesting undocumented features of webOS (3.8 specifically, on early 2018 4k LG TV) and other development-related tips.

Homebrew app ideas

• OpenVPN frontend (OpenVPN itself is easily buildable and runs on webOS TVs: https://discord.com/channels/407937994037919756/835489130967859251/906943542457401395)
• App autostart manager - dynamically update arbitrary app config and register it as input (see Registering an app as an input)
• webos-vncserver frontend with autostart option
• Package hyperiond into Piccap directly
• Quick Screenshot (expose HTTP port that just returns PNG of current screen contents)
• Custom IR remote codes editor/updater/blaster

Replacing Netflix and Amazon keys of the webOS LG TV LG Magic Remote with other apps

This procedure allows substituting one or both Netflix and Amazon keys of the Magic Remote Control Unit with other apps or TV control menus of the webOS LG TV.

Netflix and Amazon keys can be found just over the Red-Green-Yellow-Blue color buttons of such remote.

Assumption for this procedure is that you accept to uninstall the apps related to the keys to be substituted. Example: if you want to replace the Netflix key, you need to uninstall Netflix (possibly, you are not using Netflix if you do not need such key).

To uninstall Netflix or Amazon Prime, press the Home key of the Magic Remote, select the "LG Content Store" app, press "APP" at the top of the screen, press "My Apps", press the "Rem

Playling a link with standard LG webOS player

• id - id of the player app, com.webos.app.mediadiscovery for webOS 6+, com.webos.app.photovideo for webOS 3.x-5.x, com.webos.app.smartshare for webOS 1.0-2.x
• fullPath - url of the video file
• fileName - name of the video displayed in player. Filename is remembered by the player to continue playback from exit timestamp
