When launching Just Control for the first time you will be asked to select a multi viewer layout, after configuring a Device with the Setup Wizard. You can save and adjust this layout (Template) later at any time. Furthermore you can reset the given layout to start from scratch and it is possible to split and join Channel Viewers depending on the given Screen Resolution.
...
Once you are done with the Device Wizard, you will be asked to select a multi viewer layout for your just:control Just Control Template. Use the mouse to select the appropriate number of Channel Viewers and then click into the bottom right Channel Viewer when you're done. Here are some examples:
...
In this example we use a 2x2 multi viewer layout. If the connection to your Device has already been established, you can connect Channels from the Connections “Connections” Tab (Inspector).
...
Open the Inspector by clicking on the highlighted blue icon on the right side of just:control Just Control and switch to the “Connections Tab” tab. Then you can add available Channels to the Channel Viewer Area. Just drag and drop a Channel to a free Channel Viewer.
...
You can split each Channel Viewer into four or more Channel Viewers to be able to add more Channels to the multi viewer area. You can either use the “Split “Split To 4 (2x2)” or the “Split “Split To Any” Any” option within the View Menu of Just Control.
...
Select a Channel Viewer and select “Split To 4 (2x2)” within the View Menu or use the keyboard shortcut “Command-Shift-SS” to split the selected Channel Viewer to four new Channel Viewers.
...
You can do the same step with already connected Channels.
Channel Viewer - Split To Any
Select a Channel Viewer and select “Split To Any” within the View Menu or use the keyboard shortcut “Command-Option-Shift-SS” to split the selected Channel Viewer to multiple new Channel Viewers.
...
Select a Channel Viewer, go to the View Menu and use the Join option or use the keyboard shortcut “Command-Shift-JJ” to Join specific Channel Viewers.
...
In order to reset the current layout, use the “Disconnect All and Reset LayoutLayout” option in the View Menu of Just Control. This option disconnects all currently connected Channels and resets the current layout, so that you can start from scratch with selecting a new multi viewer layout.
