Linux Must Have Applications

Must Have for My Need

1. TimeShift
   System backup with snapshots for easy rollback
   Other backup solution Grsync and Back in Time
2. Graphics Software
   Inkscape, Gimp, Krita, 
3. Web Browser
   Google Chrome, Mozilla Firefox
4. Productivity Suite
   LibreOffice, Google Apps
5. Audio & Video Editing
   Audacity, KdenLive
6. VLC Media Player
   Obviously VLC has dominated the market with the codec compatibility, but more importantly for me was the ease of creating your own theme.  I have a killer theme customized for me so I love using it and provide me with some pride and accomplishment.  "Self pad on the back so to speak"
7. Veracrypt
   Disk encryption software
8. KeepassXC
   Password manager to help manage your hundreds if not thousands of passwords
9. FontBase
   There are literally thousands of fonts in the world and will be in the millions soon so it's important to have a font manager to help in the graphics designing.  The most important is that you dont need to install the font onto your system which in turn will help with performance overall since the system does not need to preload all those fonts.

Nice to Have

1. PlayOnLinux
   Install Windows application using Wine with ease 
2. Windows Games
   Lutris.net has tweeked Wine and uses things like forStarcraft II  uses DX9 to OpenGL - 64 bit - Wine Staging + Esync.  Other games will have other dependencies to optimize that particular game.
3. Thunar Bulk Rename
   Just like the name suggested, it gives you the ability to rename filenames in bulk based on patterns 
4. Konsole
   Terminal with the special ability to clone your commands from one session to another.
5. BeyondCompare
   Find and merge differences in files

This list is not complete.  I will be updating throughout the next month as I see the regular use of some of these tools.
