Never mind, I found out I have to go into each app that I want to ignore and add Alfred:ignore to the comments section of it's info pane.
Nice one. :/ and thanks for adding a simple ignore section to the preferences, I'm sure it would take months of work to add something as simple as that.
Also: I tried adding workflows to get youtube to load in a different browser (because the websearch section of the prefs doesn't allow this simple functionality of being able to choose a browser) and guess what, it didn't work because programmers didn't put in a simple reload cache button.. .
What happened, did the programmers become lazy (after getting alfred to do everything for them) that we users have to do crazy customisation just to get simple functionality?
Anyways nothing I tried worked so I browsed online for hours only to find I needed to simply restart the app..New users are experiencing this frustration with this app every day, a little beta testing might be in order. Ignore, delete or make excuses for this as you probably have with all the others that have voiced concerns, I'm giving the alfred app another go because it genuinely is an amazing app that makes life easier, the initial setup is a pain in the proverbial though but I'm sure I'll get the day that I've wasted on this back through minutes of productivity and ease of use.
