Selecting line width with the Find Dialog, it could be really good

[Tommy Hjalmarsson]

In Adobe Illustrator you have the option to select strokes by width, very useful. If you for example do a print and find that the contour line is to weak, you can easily select all contour and change the width.
The Find Dialog can do a similar job in IncScape, but poorly.
Problems.
One of the problem is that in the SVG XLM code for line width 1px is coded as [stroke-width:1], not [stroke-width:1.00], so you get a hit on 1.5 and 1.848854 also, when you type [stroke-width:1] in the Find Dialog/Style text field.
In the SVG XLM code the next sign is ” after the stroke-width number , [stroke-width:1”] or [stroke-width: 1.848854”]. But you can't use the sign ” to narrow the search. (“ defines the end of the Attribute, or the beginning of a new code string in XLM code.)
And when all search field is checked and you search for line width, it's hardly work like the utopia I dreaming of. Not at all.
When you have the InkScape Preference option: InkScape Preferences/Tranform..............uncheck ”Scale stroke width, it scale lines anyway. Your 2px line can now be 1.935637 or 2.136549 (the number is just to illustrate) Bug #830997

So if you work in discipline manner, it doesn’t help. You perhaps dont't get a hit on 2px line width because it's 1.935637 .
Now Geany it's better for batch change the line width than InkScape are.
-My simple ideas-
( in this example lines is separate without filling, and filling is without line. Think cartoon with line and color separate )
In Objects Properties you can give a object a Title. Let say you could select a number of lines and give them all a title as “thin line” or “contour”. ( Objects Properties can only assign one selection now, but if just Title could do more) And if “Find Dialog” also had the option “search Title” I could search for the contour title and my utopia is nearer.
Or...
InkScape have defined line width as 0.1...0.25...0.5...0.75...0.1..1.5...2...3 and so on, if you choose that . Let say I could lock InkScape to only use the defined line width for a document or in InkScape preferences. And InkScape also created subgroups as for example stroke-width:1.5, that I could choose and batch change the line width. And perhaps also force InkScape to only write the defined line width, and with only two decimals in the XLM code.
Work more on Find Dialog, it have big potential that can lead to new useful function.

Please take a look at the current development version (see inkscape.org/download)
New menu item "Edit > Select Same > Stroke style" includes stroke width (bug #170378).
