Update (04/05/2023) - with HD themes being the way to go now i have removed some of the old options which aren't really useful anymore to simplify the look as well as redid the readme so it's focused on just what you need to do in order to apply a theme.
Also had a few users comment that when trying to adjust the font colors it would crash because of the online color wheel element so i have removed it and just added a link to the one i was using so there shouldn't be anymore crashes due to that.
I have also altered the Apply button for importing a custom HD font (older fonts also work) in Advanced ~ Customize Options so rather than you having to manually place the font in the correct place it will bring up a window for you to select the font you want and put it in the correct place and name it correctly for you.
New themes, vmu icons, a color preset and a font has also been added.
Update (22/03/2022) - Fixed issue with downloaded themes not going where they were supposed too as well as added whether a theme is hd or standard to the general theme details.
Update (09/03/2022) - Fixed issue with hd themes not being copied over.
Update (03/03/2022) - Fixed issue with connecting to server.
Update (24/11/2021) - Updated GDMenu Theme Preview Generator to v1.01, All issues should be fixed now with converting the theme to OpenMenu.
Update (17/11/2021) - Accidently had the HD theme previews saving to the wrong folder, That's fixed now.
Update (11/11/2021) - Updated GDMenu Theme Preview Generator as the bottom half of the app was being cut off on lower resolutions.
Update (10/11/2021) #1 - Updated GDMenu Theme Preview Generator to add the needed header to the OpenMenu PVR files.
Update (10/11/2021) #2 - Updated GDMenu Theme Preview Generator to support converting the theme to an OpenMenu compatible one, The theme will replace the OpenMenu GDMenu one and you can find the two pvr files for it in the OpenMenu Folder.
Update (05/10/2021) - Made a small change to how theme previews are done to try to help speed up the previews for HD themes.
Update (16/09/2021) - Updated my theme preview generator to allow you to show/hide the disc info since that is something you can disable in my theme manager.
Update (15/09/2021) - Fixed an issue with HD themes no longer importing.
Update (14/09/2021) - Added an RGB color wheel to the 'Font Colors' section so it's easier to pick the color you want.
Update (13/09/2021) - Added the online HD themes to the main selection list so it's quicker and easier to apply one by simple doing what you'd normally do for a standard theme, Because of this i have removed the online section on the 'HD Theme Selector' however i have left the offline section so you can still use this to import your own HD theme.
I'm also using .Net Framework 4.8 instead of 4.7.2.
Update (09/09/2021) - Updated the theme manager app to show the preview of the hd theme you have selected as well as the filesize.
Update (09/09/2021) - Updated my theme manager to be able to better preview the HD themes as well as download them from online so any theme i create or others create and send me i can add to the online section and they will simply appear on the app for you to download and use. (Clicking download will automatically apply that theme as well so you won't have to do that after)
Also updated my preview generator to version 0.6c and changed it to save the images as jpg, i have been messing around with it lately and that just seems like the best format to use overall given it is just a preview.
UPDATE (08/09/2021) - Fixed an issue with my theme preview generator app which caused it to take longer to close, I also had an issue with some of the preview png files so i changed the resolution to 960p and format to bmp.
I also added an Illbleed HD theme i just made.
UPDATE (07/09/2021) - Removed some of the editing options as they were breaking others, I also tweaked the sizes of some of the menus and moved a few things around.
Also added a green version of my hd pso theme a long with a green font color preset as well as a spongebob hd theme 😀
