 Is it possible have a layout or profile set so when in a raid group (mythic, flex, etc), I can set it show only my group?  Right now, I'm manually selecting the group number I'm in under General - Layouts.  I have it set to 1 Column, 5 Units but it wont default to my group. I dont want to see the whole raid as on this toon i'm dps and dont really need to.   I see options for sorting by Group, Class etc

This can be done creating a user defined layout in version 2.0.1-alpha.

Goto the layout editor create a new layout, add a new "custom" header to the layout (+ tab), in the "Units List" option type:

player,party1,party2,party3,party4

Then configure the addon to use this new created layout for raid groups.

Trying to set this up now as described

I have a Theme setup for Raid, then I went to Layouts -> Editor, created a new Layout called User, left everything checked under Groups and Roles and then put player, party1, party2, party3, party4 into Name List. Theres only one tab, players(1)

it's still not showing my current group (for example, i'm in Group 4), its only showing me the first 5 people in the raid 

You have to create a new header, (you cannot use the default "players" header, because the name list option only accept player names, not unit names).

1. Click on the + ("plus") tab (red arrow on the image below)

2. Select "custom" header type.

3. Click Create Button

This will create a new "custom" header/group, in this custom header add the units to display (player,party1, etc). Probably you should enable the "hide empty" option too, to hide non existant units.

Finally you must remove the "players(1)" header, so click on the "player(1)" tab , scroll down to the bottom and use the "delete" button.

After deleting the players(1) header, the layout editor must display only the new custom header: "custom(1)"
