Ah Memories!
We started with PFS:Write and MagiCalc on the //e, in the wonderful world of 80 column text. Then moved through AppleWorks and into Claris, also using ClarisCAD and FileMaker Pro.
Hypercard anyone? 🙂
Today I am doing a lot with LibreOffice. I use the drawing module as a replacement for Visio. I have noticed a performance drop on my MacBook Pro (2013, Sierra) especially when an external screen is attached. I find my LibreOffice Drawings to preform better without the external monitor, so I think that something in the video code is bunged up. On my iMac 27" (2010, High Sierra), video performance is much better.
OpenOffice Draw doesn't have this issue, but the colors on my drawings change, so I don't use it as much.
I have Mac Office 2011 that I won't upgrade. It is paid for, and still works, and is onboard only for PowerPoint. I do enough presentations at trade shows that I need it to be exact. I won't be moving to Catalina anytime soon.
