The linux setup for everyone (freeware with GUI only and distro recommendations)
THIS LIST HAS BEEN DELETED DUE TO A BUG, SO IT MISSES SOME HONORABLE MENTIONS !
I've been using Linux for a year now. I do use CLI tool and the terminal but I'm super used to GUI and I do understand why you might don't want to bother with Terminal and stuff ! Here is my list of useful tools for beginners on Linux !

Powerful Open Source Creative Softwares
Ever wondering about free great open source software to start your idea? Here's a list for you to get started.
Also mentions several rarely known and newer software as well!
Please note that almost none of these alternatives are 1-to-1 replacement with exact some features. Most of these software might have entirely different scope of project.

Working in the creative industry but don't want to use Adobe products?
For quite a long time, I've been looking into entirely ditching Adobe Creative Cloud products because of the price (€60/month), the subscription model, the fact that you have to use their Creative Cloud in order to use their software and to sync anything, the way Adobe Photoshop, Adobe Illustrator, and Adobe InDesign are bloated, the fact that often you can't use the software if you don't have an Internet connection because Adobe must be able to check your license… and so on and so on.
For a long time, their software were amazing and above everything on the market, but now, Adobe software feel like old complicated bloated tools to me. And, so I took my courage with both hands, uninstalled all Adobe products on my computer, canceled my subscription and deleted my Behance and Adobe accounts.
I've since then replaced all Adobe software with the following ones:

It is a very good alternative to Sumatra, and evidently its greatest advantage over this are the PDF annotations. Some functions that I use a lot in Sumatra and that are NOT in Okular are:
Open multiple files in tabs, in a single window. Okular works Office style, it will open one window per file, which is not practical.
File history, and possibility to reopen them ALL automatically when starting the program.
In the Windows version, Okular occupies more than 400 Mb, while Sumatra less than 20 Mb.
Finally, a very commented problem is the lack of a "standard" installer in Windows. I had the same problem, and after abandoning all this and trying MuPDF (quite limited) I gave it a last chance, and it turns out that IF THERE IS an installer that is very hidden...the link is below.
There you will find the typical *exe, and also a 7z compressed that will make the portable version (the executable is in the bin folder). If you navigate within that web, you will also find the "Nightly" versions of Okular, and also other applications of the KDE community
Mensaje Original:
Es una muy buena alternativa a Sumatra, y evidentemente su mayor ventaja respecto a esta son las anotaciones en PDF. Algunas funciones que uso bastante en Sumatra y que NO están en Okular son:
Abrir múltiples archivos en pestañas, en una sola ventana. Okular trabaja al estilo Office, se abrirá una ventana por archivo, lo cual no es práctico.
Historial de archivos, y posibilidad de reabrirlos TODOS automaticamente al iniciar el programa.
En la version de Windows, Okular ocupa mas de 400 Mb, en cambio Sumatra menos de 20 Mb.
Finalmente, un problema bastante comentado es la falta de un instalador "estándar" en Windows. Tuve el mismo problema, y tras abandonar todo esto y probar MuPDF (bastante limitado) le di una última oportunidad, y resulta que SI EXISTE un instalador que esta muy oculto...lo encuentran en:
https://binary-factory.kde.org/view/Windows%2064-bit/job/Okular_Release_win64/
Alli encontraran el típico *exe, y tambien un comprimido 7z que hará las veces de versión portable (el ejecutable esta en la carpeta bin). Si navegan dentro esa web, también encontrarán las versiones "Nightly" de Okular, y tambien otras aplicaciones de la comunidad KDE.
Although this might have been true in the past, today Okular does support tabs. You can enable it in the settings.
Thanks @Brouware. You are a life saver. :)
Okular on Windows does not support epub. Source: [https://forums.linuxmint.com/viewtopic.php?t=195708](https://forums.linuxmint.com/viewtopic.php?t=195708)
I don't know its .pdf capabilities.
thanks kde to give a good and really lightweight pdf viewer on windows :)
There's a lot to like here, because it is a competently assembled and FOSS reader that does PDF and markdown. But on PDFs, the use of forms - which is my main reason to interact with PDFs - feels hopelessly clunky for now, superimposing giant text boxes over the PDF instead of transparent guide boxes. If you don't edit PDFs as much as I do you may still like it, and I'd certainly fall back to it in a pinch, but it's just a little too intrusive on that one thing for me.
Open Source and Free, it looks like a good choice for editing PDFs. If you look far right on the pull down menu under highlite, you will see a text option. Does not open .rtf files. Another perhaps much more lightweight and free option with similar abilities is
Ashampoo PDF Free
Lightweight and have a text highlighting feature.
Hope in the future have a merge and organize pages.
Good software but still can't edit text.
