MELLEL 4.0 AND BEYOND!
Mellel is now a veteran word-processor - It's been in the market for almost fourteen years. This is the right time to re-invigorate it, break new grounds, and expend its capabilities.
Mellel 4.0 will play a key role in the regeneration of Mellel, introducing a host of new features that we believe will awe you, and even better: will cause you to think: why didn't anyone else think of this?
Return to Upgrades
But before we get into all this: Mellel was always an upgrade product. That is, when you've purchased it, you got a license that allowed you to update Mellel for free for a limited time (in most cases, two years). In 2011, we've decided to change course, and for a while offered lifetime upgrades. We now believe this was a mistake, that did not benefit you, Mellel users, and did not benefit us. We intend to change course and re-install a for-pay upgrade policy.
A for-pay Upgrade policy is fairly simple: when you purchase Mellel, or if you've already purchased Mellel, your time-stamped license will allow you to get free updates for two years. Beyond that, you'll be able to keep your copy of Mellel and use it (and download fresh copies of that version) but to get to the latest version and two more years of free updates you'll need to pay an upgrade fee.
If you purchase an upgrade to Mellel now, you'll get two years of free updates! That is, a free upgrade to Mellel 4.0 and beyond. We try to be fair as possible, and so even if you've purchased or upgraded Mellel before this announcement (i.e., a month ago or a year ago) you'll also get two years of free updates, which will also allow you to upgrade to Mellel 4.0 for free.
Should you upgrade now? In many cases, the answer is yes. If you're testing Mellel, or if you're an existing registered user, purchasing or upgrading now is the safest way to go, allowing you worry free transition to Mellel 4.0 and beyond.
We will add some details and specifics about upgrades on our site in the near future.
Important note: Users who received a "life-time free upgrade" promise will NOT be required to purchase an upgrade... A promise IS a promise.
What's in Mellel 4.0 and beyond?
Mellel 4.0 and beyond (some features will be rolled-out with Mellel 4.1, 4.2, and so on) will introduce a mix of ground-breaking new features, a huge number of updates and enhancements to existing features, and a much needed interface overhaul.
Index: Mellel 4.0 will introduce a revolutionary indexing tool, that goes beyond anything now existing with any other application. Essentially, you'll get all the features you can now find with top-of-the-line index-creation applications (which sell for USD200, by the way), but with the flexibility of live text, quick marking within the text, auto-marking (e.g., of any related term), and so on. In addition to all those, you'll be able to create multiple indexes and move items back and forth between them, add comments, and images, tag icons and mark index items, manage items by drag-and drop, and more.
A New Interface: This will probably the most evident change with Mellel 4.0, and we hope to get it a step beyond just changing the appearance of Mellel, introducing usability enhancement (for styles, saving, filters, easy organising of sets, and so on.
Topics: Mellel 4.0 and beyond will introduce a new, revolutionary new feature of topics. Using topics will allow you to organise your work not just chronologically (e.g., by headings in the document) but also by topics) but also by subject-matter, by characters or cited sources, locations, and just about any other way you wish to organise your document. In addition, you will be able to organise your document by time, turning your outline to a timeline. We cannot promise we'll have all the features ready for 4.0 (some of them seem a bit iffy at this point), but we'll get them all gradually.
Legal Numbering (done right): Here we plan to offer legal numbering with a twist. That is, not simply having the options, but making the writing of legal documents a breezy, automated experience, with emphasis on minimal hassle.
Outline redux: Mellel's Outline is one of its strongest features... And it's going to become much stronger, with an outliner-like interface for quick outlining, adding comments, icon tags and markers to auto-titles and tag levels. With upcoming updates to Mellel the outline will enable you to organise items not just as a list, but also in a story-board fashion, and other methods.
Captions: Another feature we plan for Mellel-the-next-generation are smart captions to images (and probably other items), including multiple captions, captions above, below, to the left and right (e.g., when you need a regular caption, but also a credit caption), and much more.
And much more: There are many more features we plan to introduce with the upcoming versions of Mellel — some are new, some are most-requested fixes, and some are simply meant to catch-up with the times and with features that got left behind. Some of the hi-lights here are: expended import and export options (docx, ePub, html), a smart auto-replace, revamped and modernised tables, shapes, filters for enhanced internal-search options (e.g., with cross-references). vastly improved character style options, enhanced footnotes and endnotes, and much more.
