The ODF standard supports [1] six alignment settings for text in a paragraph: * start * end * left * right * center * justify At the moment, LO "supports" four of those, and actually - doesn't even really support those four: * There is no UI in the Paragraph Style / Paragraph Formatting dialog choosing Start or End alignment. * When choosing Left or Right, LO often (always?) actually chooses Start or End, in terms of what's written to the ODT file. For example, if you create a Writer document with four paragraphs: LTR,left-align, LTR,right-align, RTL,right-align and RTL,left-align (with the first one inheriting the page style), you get this in an FODT output: <style:style style:name="P1" style:family="paragraph" style:parent-style-name="Standard"> </style:style> <style:style style:name="P2" style:family="paragraph" style:parent-style-name="Standard"> <style:paragraph-properties fo:text-align="end" style:justify-single-word="false"/> </style:style> <style:style style:name="P3" style:family="paragraph" style:parent-style-name="Standard"> <style:paragraph-properties fo:text-align="end" style:justify-single-word="false" style:writing-mode="rl-tb"/> </style:style> <style:style style:name="P4" style:family="paragraph" style:parent-style-name="Standard"> <style:paragraph-properties fo:text-align="start" style:justify-single-word="false" style:writing-mode="rl-tb"/> </style:style> So, let's do the following: * Have the UI show all six options, at least when RTL support is fully enabled. * Save what the user has actually asked for, to the file. * Rework the four-button group of alignments into a six-group button, with the appropriate names, tooltips and help text. The dilemmas are: 1. What to do when RTL support is _not_ enabled - whether to maintain the "Use Start even though the user said Left" convention. 2. Whether to show the six buttons on the toolbar, only only the 4 buttons of S,E,J,C and keep the other off the toolbar by default. 3. What button images to use for proper Left and Right vs Start and End. [1]: ODF standard 1.4 schema, 20.223 fo:text-align.
