People who I don't know sending a random 'HI' and no other info about wtfh they are reaching out to me about. Or classic hey I opened a ticket not two minutes ago ' can someone look at this ticket pleaee' blah blah blah blah. Idiots who message direct over chatting in the team channel for stuff that should be seen by the whole team working a ticket.

I worked oncall before so the slightest him of my cell at night will wake me up.ДЄnother annoyance on messaging. It has this Bullcrap Send Anyway function on messages which totally overrides my Do Not Disturb settings if said moron is blind of what time they are sending their damn message. I work for global company and I constantly get messaged after midnight by morons who think i am up at 3am

The inability for the app to BLOCK DIRECT MESSAGING when outside work hours. You really want to know what I hate about SLACK. I mostly like Slack but for remote teams this is a problem. So it's not the inherent bandwidth and processing power required. A video call with the same number of people in a true native app is not a problem. Video calls (using the 'native' app on macOS) consume so much resources that the whole machine becomes unresponsive. (or, to put it another way, if you start a channel call, you should be able to moderate it and remove those from it who are to meant to be there) You can't remove someone from a call if they join by mistake It's slow and laggy if you ever used a native program and got used to responsive user interfaces. and that stuff is still pretty bad, even tho it was changed a bit. I used to really hate slack, but that's mostly because I have to use user groups a lot, most of the time I'm using slack it's to find someone who belongs to some group and message him. Especially when time and date stamps are so tiny so it takes a while to get oriented again. Scrolling needs to be improved, I don't want random jumps there. What a waste of time compared to other tools which are supporting this.Дate stamps needs to be more visible, or give us option in settings to make it more/less visible I'm sick of searching that person, which closes user groups and if that person is actually AFK, I have to search for that group AGAIN and do it again. If I search for a group, open it, I want to be able to not just see who is online from that group, but also a message button. I miss some features but I wish slack had a little more ability to organize, group channels, and navigate a little better. The red dot number keep climbing even though I've read everything and used shift-esc. Usually shift-esc will clear it (in itself a pain), but now even that hack won't help. No way to forbid slack to touch my microphone settings (seriously, dont autoadjust my microphone level, it never works and i hate you so much for it) Interface ist inconsistent between devices.

Give me some freaking organization and curation to the conversations - otherwise it's 1000 person cocktail party with everyone playing drinking games.ДЄGAIN! Search sucks. Break up the people into a separate window so I can have a buddy list ala Communicator or Skype. it got better with ctrl f in conversations, but still isn't thereД«adly arranged Chinese buffet of people, conversations, channels, files and links. If they could figure out search, Slack would be unstoppable. It's so bad I am considering making my own mix of discord and slack.ДЇinding conversations you know you've had - but search is (Still) terrible, and if it was a direct message with a group of people, you have to remember exactly which group of people it was with They are unstoppable towards companies who don't have people technically savvy enough to transition any other software. Even though I use it as an integration for another platform and will recommend it even though it's horrible as a whole. Let me rant about everything I hate about slack. Slack is one of the worst messaging apps I have ever seen. The awful crappy dependency hell of a thing they call an API. API integrations are possible over at Discord. It can be intergrated with discord to work with clients who only want to use slack or even any other platform. I still use slack, although I prefer discord.
