Swiss Army knife for words - Excellent !

Underwhelmed when I first tried, but now with more documents under the belt, omniout6 is proving the fastest way to transport to a rough spot, and tweak!

Viewing scale adjustment on the fly (I can do on my mac) is what I miss. But it’s not a dealbreaker.

Pinch and zoom, for true focus and comfort would be great. This avoids changing a document property, font size - I’d rather fonts fixed for consistency.

Otherwise I highly recommend this precision tool.

Couldn’t live without it.

I "run my life" off OmniOutliner. I'm a web developer, and use it to maintain information and action items for all my client setups, all my work projects, and all kinds of history relevant to both work and my personal life. It lets me organize all the thousands of bits of information that otherwise would be too burdensome to save and too difficult to find or reference.

I've used many different outliners over time, but this one is by far the most mature, comprehensive, and bug free.

Outliners--including this one--are generally advertised as planning and brainstorming tools. That, in my opinion, drastically under-advertises their true capabilities as a way to maintain and organize all the miscellaneous information we need a way to safely and conveniently save, organize, and reference every day. OmniOutliner is probably the single most important piece of software I use.

I'm using the Pro version. It does cost a few bucks, but for me it's paid for itself many times over.

(And no, I don't work for or have any kind of connection to Omni other than being a paying customer. :) )

Purchased ..trending up !

I have now purchased omnioutliner 6 (raised star up one).

For sequencing information, and steering with keyboard shortcuts, it has no peer. “Focus” on a line has always been wonderful.

Also the iPad version has removed the orange tint, which was too pungent and broke my focus.

The crashes appear centered around larger documents with images and pdfs. So improvement needed there.

10 Crashes per hours (first day)

I have now got the demo running with the professional version.

On simply moving the cursor highlight, or working on content I am getting crashes like clockwork..

The concept is great and a more reliable version would be nice. Every time it crashes I lose a bit on activity of the last minute..

I’ll need to go back to outliner prof 5

BTW a better reporting method for crashes is needed. Omni is missing a LOT of crash piggybacking on users email.

Why isn’t omni login collecting crash info?

For Apple crashes it’s a snip to send out bugs without email.

Response from developer

Sorry for the trouble! We'd love to figure out why OmniOutliner 6 is frequently crashing on your Mac (we're not aware of a bug on currently shipping operating systems that could be causing this). Email is the best way to get ahold of our Support team at this point in time - if you could drop them a line at omnioutliner@omnigroup.com, we should hopefully be able to get this issue tracked down! If you do happen to be running OmniOutliner on a beta of an upcoming operating system, test build of OmniOutliner 6.3 with compatibility updates are available on our website: https://www.omnigroup.com/test/

Must have app for structured thinking

Hi, this is a must have app helping you to think in structures. Absolutely love it and use it for almost anything.

To bad the support does not react to my technical issue regarding copy and paste.

Response from developer

Thanks for taking the time to share your positive feedback about OmniOutliner! Hopefully the additional info our Support team has now followed up with resolves the issue you were encountering. Our apologies for not supplying this information about the distinction between pasting into a row vs. into the outline sooner!

Solid, Reliable.. Better Than 99% of Other Apps.

OO has come a long way over the years. The current iteration is top quality, and the UX/UI is for me, without any defects. The 2* review is a bit confusing and certainly does not replicate anything I’ve experienced. The ratings on this app were 4.5* last month, I’m unsure how it’s dropped on one review to 3.7*. It’s a great app.
