Its possible to select one or more configurations for editing.</p> |
| <p>But, then we deal with string list property values, it is not obvious how to concatenate them, if they differ.</p> |

| <td headers="option"><strong>String list Display Mode</strong></td> |
| <td headers="description">Specifies how values are shown. The two options are: |
| <ul> |
| <li><strong>Conjunction</strong> shows common elements only, so if 1st configuration has |
| value <A, B, C> and 2nd configuration has <B, C, D>, <B, C> will be shown. |
| <li><strong>Disjunction</strong> shows all existing elements except doubles, so if 1st configuration has |
| value <A, B, C> and 2nd configuration has <B, C, D>, <A, B, C, D> will be shown. |
| </ul> |
| Note that Display mode can be changed directly on each tab which deals with string lists. |
| Result is immediate: data on the tab is refreshed according to selected mode.</td> |

| <tr valign="top" > |
| <td headers="option"><strong>String list Write Mode</strong></td> |
| <td headers="description">Specifies how values are saved. The two options are: |
| <ul> |
| <li><strong>Modify mode</strong> adds, changes or removes elements affected by user's actions. |
| Elements which were not touched by user are left unchanged.<br> |
| Example: cfg1 has <A, B, C>; cfg2 has <B, C, D>.<br> |
| User removed B and added F.<br> |
| Result: cfg1 has <A, C, F>; cfg2 has <C, D, F>. |
| <li><strong>Replace mode</strong> puts currently visible elements to all configurations. |
| Old contents will be lost.<br> |
| Example: cfg1 has <A, B, C>; cfg2 has <B, C, D>.<br> |
| Visible list depends of Display mode: <B, C> or <A, B, C, D>.<br> |
| User removed B and added F.<br> |
| Result: both cfgs will contain either <C, F> or <A, C, D, F> depending of Display mode. |
| </ul> |
| Note that Write mode can be changed directly on each tab which deals with string lists.</td> |
