What business software app do you hate the most? Why?

I don't particularly dislike PowerPoint, but I can't resolve the fact that in 30 years of development and massively increased software footprint, the presentations look the same now as they did in the 90's. The only thing differentiating the age of a presentation is the choice of default font.

OTOH I have a friend who would argue this is a sign of perfect design, and the amount of hard drive space a software package takes doesn't matter so much these days anyway. Six of one, half a dozen of the other.

SharePoint. Mostly because we use it improperly (as a backend for web apps)

Jira. So slow these days.

- WYSIWYG editors (confluence, google docs, word, etc.): never does what I want, pasting markdown or HTML always fails and at some point I get bugs with nested lists...

- MS exchange: forces you to use outlook and is buggy

- Linux: Bluetooth headsets stuck to 8bit (instead of 16bit) when using them with mic, external sound card not fully supported, encryption not coupled with user login (and using suspend to ram makes it useless)

- Windows: Backups suck (built in can silently fail, no user folder etc), pushing Edge hard, not unix

- macOS: the dock, can't switch between windows of the same app efficiently, hard on exotic keyboard layouts, bad font rendering on non-retina screens

Probably Workday. It takes more clicks to get where you want to go than older, less flashy software. Rendering and response times are slow too. It might just be how my company set it up.

MS Teams is pretty terrible, probably worse than SharePoint for me.

Lync for sure. Or Skype for Business as they call it these days even though it's got absolutely nothing in common with Skype. Worst communications app ever created.

Slack - horrible search

Any shipping software by DHL, FedEX or UPS. This stuff is horrible, clunky, error prone, ignores productive software conventions, transfers data at a snails pace etc

Dell KACE, what a piece of utter garbage.

Cyberark

Very slow and un-intuitive/convoluted UX.

Any CRM app.
