eNO is our own copyrighted UI where we have integrated WHMCS admin theme to build adeno template.
And one more thing, please take a look at our eNo client area template. You'll know what we are and what we do. and if you want to see our full admin UI.
If you know, nobody can sell others UI in big marketplace like Template monster, envato etc.
As far as LARA is concern, It is based on someone other's admin UI please find link below.
The common things you're talking about are always find similar in every WHMCS admin theme/template because they all have similar features and functionality as per WHMCS because WHMCS doesn't allow so many possibilities of modifications in admin section by tpl files, there are very few things which you can edit/modify.
