This sounds great. Will check it out 👍

Just to clarify what others are saying: the 'software store' (Discover in your case) is just the graphical application that you use to manage the software installed on your computer. The repositories, aka 'repos' are the sources of that software. There are people whose job it is to vet the software in those repositories and make sure that it's safe. Flatpak is a packaging format. The biggest repository (and what you likely have enabled) for flatpaks is Flathub. If you're installing software from the Debian repo and Flathub you should be fine. You should be able to verify which repositories are enabled via the Discover app. You have the freedom to add other repositories too, but it will be your own responsibility to evaluate whether those sources are trustworthy if you do.

Long story short, if you just use Debian as it is, you are fine.

Don't worry, I get KDE updates in GNOME.

Ah good old flatpak strikes again.

I'd forgotten that flatpak is a pain for this and I ended up manually working around it.

I'm thinking of adding the following to the download page:

"When installed via Flatpak, GIMP folders can be hard to find. I recommend creating your own folder for downloaded themes and adding it to GIMP: Create a new folder e.g 'my-gimp-themes' somewhere that makes sense to you and then place the unzipped PrintroomExpertSuperflat folder inside it. Then, in GIMP, go to Edit > Preferences > Folders > Themes, click the 'Add a new folder' button on the left and then the 'Open a file selector...' button on the right and select your my-gimp-themes folder. Finally, click the OK button. New themes will become avalable after restarting GIMP. All further theme downloads can be placed in the my-gimp-themes folder."

Would you mind letting me know if that makes sense and works for you? Thanks!

I made a theme which is more professional-looking and less busy/cramped if you're interested:

I'm about to release a dark version of it too.

The fact that this word needs explaining to 99% of the world's population tells me that it's not much of an issue.

I love how much simpler it is in this release to make independent effects/adjustment layers. You just make a group layer and set the mode to 'Pass through'. Then the adjustments/effects/filters you put on it are a) applied to all layers below it b) fully non-destructive and c) can have their own mask.

The number of adjustments you can make non-destructively - and have full control over - makes GIMP 3.2 the most powerful non-destructive editor that I know of.

There are some really nice film simulations in Rawtherapee under the Colour tab and I would try this first. I personally really like the Polaroid ones.

Another great (and very flexible) option is the G'MIC plugin in GIMP. Go to Colours > Colour Presets and try some out. You can add and configure grain under Filters in GIMP. This might be a good option if you want lots of control and are willing to learn a bit.

Feel free to send me a message - I help people get up and running with free and open source photography software.

I use Libreoffice for all of my business admin, from invoices to pricing models. It's fantastic software.

Have a look at Debian. If you set up Flatpak with Flathub (very easy) you can easily install all of the applications you're likely to want with the GNOME Software GUI. Debian is a community distribution.

I had a similar thing. I started using Linux for privacy reasons and over the course of replacing all of the proprietary software I was using I fell in love with FOSS. Especially GIMP and other photography-related software.
