Accordance is well equipped to function completely without an internet connection. The only exception to this are trial/time-limited accounts (which I'm sure don't apply to you), or accounts currently on a payment plan, as a protection in case the payplan defaults. Once the payment plan is finished, or the trial account transfers to a permanent one, then Accordance has no further internet restrictions past a one-time initial setup.
Regarding many of the interface points here, many if not all of them can be accomplished in Accordance. Often, however, it won't be exactly as BibleWorks did it, so I do encourage any new Accordance users to experiment with the program, keep asking questions, and learn the Accordance approach to bible study. We have a huge amount of training material available (podcasts, webinars, live training, tutorial modules, etc), and I highly encourage new users to check them out.
Addressing a couple of the interface comments:
The Graphical Search Engine in bibleworks makes visualization of a complex search much easier than the multiple linked window approach in Accordance, but accordance seems to be faster when there are many <AND> or <OR> conditions. Bibleworks is pretty fast if there are less than three in a single branch but gets exponentially slower as more items are added into that branch.
I encourage you to check out Accordance's Construct search - its quite powerful when constructing more complex search arguments.
Note: In the Bibleworks command-line, the default search is literal, but in accordance the default search is for lexical root.
This is correct! However, if you want to do a literal ("inflected") search, simply enclose the terms in double quotes, e.g. "יָֽלְדָה֙" You can right-click a word and choose Search For -> Inflected to see how the search would be built.
One more note: In bible works, the morphology appears in a hovering window near the word where the cursor is positioned; I like this much better than the accordance option of placing morphology below.
As Michel noted, you can click and hold (or Alt+click) to get a window at the word's location with the information. Holding down Control provides statistical information and a lexicon lookup. For the instant, non-click access, you can also detach the instant details zone, placing it anywhere on your screen. You can even set it to automatically hide when not needed.
Additionally, Bibleworks provides the morphology for prefixes, promonal suffixes in the same window (without trying to move the cursor around to position it over the components of the "word." It may just be what I am comfortable with, but it seems a little better.
This is definitely a style difference, as you've noted. Accordance helps make it clearer which part of the word contains which grammatical lemma, though as you note it does require moving the mouse around a bit more. You can always make a selection and choose Amplify -> Language -> Parsing to get a full listing of all grammatical parts.
Additionally, the LXX-MT module is helpful, but would be better if it allowed linking to the Hebrew and Septuagint texts.
Which linking are you referring to? Both the LINK and MERGE commands work to bring data into the MT-LXX module, allowing for surprisingly complex searches.
One more issue: In bibleworks, I could toggle the nekkud on and off in the Hebrew text and I could search for exact phrases without typing the nekkud. There doesn't appear to be a way to do either of these things in Accordance. Is there something I am missing?
Update: I found out how to search for the phrase i.e. if you right click in the text box it gives you the option to search by "letters" (an option that doesn't appear by default in the search box). After choosing that I could search for phrases with ease. I still do not see a way to toggle the nekkud in the text. This would be a very good feature to add as some publications do not handle Hebrew text with nekkud very well. In many cases it is best to simply best to copy the text without the nekkud.
What sort of exact phrases are you attempting to search for? Can you give a specific example? The Letters search can actually switch by default (see Preferences -> Greek and Hebrew), or you can choose it for yourself on the blue menu near the left side of the search box.
I hope this is helpful! Feel free to ask any followup questions, in this topic or others. Accordance is far from perfect or able to do 100% of every possible biblical research task, but as you continue to use it, I hope you'll continue to discover the ways in which it excels.
