Edit Skin Layout?

my apologies if this isn’t the correct place to post this question….

i’m looking for a very simplified media manager layout, pretty much just for movie files, and have been able to “hide” a lot of the categories/window i have no interest in displaying… however there are a couple of more things i would like to do but can’t quite figure out how, for example removing / hiding the “categories / in progress movies / recently added movies” window….

after a quick google i came across a thread that mentioned this could be done using “the keymap way” as follows:

ActivateWindow(Videos,MovieTitles,return)
ActivateWindow(Videos,TvShowTitles,return)
ActivateWindow(Videos,MusicVideoTitles,return)

but it’s over my head…..

in a nutshell i would like:

1. kodi to show the movies window whenever it is launched.

2. remove “categories / in progress movies / recently added movies” page for movies and instead have it default to the poster wall.

3. remove the tool icon on the poster wall.

– remove / hide this page:

– have this as the default movie window but without the tool (green box):

any help would be very much appreciated…
