with latest GHL connect, I can control the LX7206 light. But compare with some leading app, I think GHL can do better. Maybe you can consider build into next App release.

-light composer is missing. Can we add? The spectrum moving over different channel ratio, is extremely useful for end user. Also pretty fun.
-shortcut/button to off turn on/off all channel. Handy on first page.
-easy button for turn on photo mode.(LED continuous on)
-show different channel schedule curve, better overview.
-button to switch off manual flash(lighting)
-option to change the background light when lighting(if making a dedicated customized spectrum will be perfect)
-why need static IP address to access light?(DHCP with dynamic should also work, refer to AI26)
-bottom navigation panel, much efficient to switching between different sheets
-add quick manual spectrum adjust mode, maybe adding save/load option. It is useful to take nice photo, video in quick manner.
