New Dynamic playlist pros and cons and suggestions

[Alexey Shildyakov]

Dear developers,
what do you think about my suggestions?

2011/8/13 Alexey Shildyakov <ashl1future at gmail.com>:
> Old Dynamic playlists:
> Pros:
> + Big design. All is good visible.
> + No addition windows. Change the values immediately.
> + More tradition KDE design
> Cons:
> - No limit to Proportion. Proportion summary might be greater than 100%.
> - No sophisticated conditions.
>
> New Dynamic playlists:
> Pros:
> + Sophisticated conditions - almost you want.
> + Limit to Proportion. The sum of proportions is always 100%
> Cons:
> - Addition windows to edit values
> - A little design. It's difficult to look at this and understand the
> percentages.
> - No percentage is shown.
> - Unusable automatic change of proportion.
>
> Thinking:
> Lets think about new dynamic playlist disadvatages.
> 1. Addition windows to edit values
> The reason it was implemented that DP become more configurable. So it is normal.
> 2. A little design.
> Design is for you opinion, but it's really difficult for understanding.
> 3. No percentage for proportion is shown. It's difficult to look at
> little design and understand the percentages.
> It's bad because there is no way to understand numerical values of
> proportions. The values should be shown in normal view and in window
> while changing.
> 4. Unusable automatic change of proportion.
> The problem the user don't understand how another proportions will be
> changed when he change one. And for me it problem when I add new
> proportion or change one - then I must change percentage for all
> proportions. It's difficult and spend much time.
>
> I suggest the user non-editable bar which show the deficiency and
> excess of summary proportions percentage. The bar width is the same as
> the width of another real editable bars but the virtual length is
> depend on number of proportions in the same level. For example if 3
> proportions are presetned, the minumum is -300% and maximum is +100%.
> If every proportion has 100%, then  this bar has -300%. If every
> proportion has 0%, this bar has 100%. The bar have the middle value
> 0%. So think this bar should be called "Proportion deficiency".
> This bar must be presented in every where proportion might be.
> The slider is automatically moves inside the bar and represent
> deficiency or excess with showed +-percentage label. So, the user can
> choose any value for any proportion when user add new or change one
> value as he want to be. The button OK in window should be disabled if
> this bar has non zero value. So, the user must manually change the
> proportions that sum of them will be 100% so this bar has 0% and the
> slider be in the middle.
> The helpers is editable proportion percentage textbox and button "MAX"
> that add maximum possible deficiency to the current proportion the sum
> of proportions to be 100%. Usually user want to decrease proportions
> manually but may want to fill remaining deficiency to up to 100%.
>
> Suggestions to improve usability:
> - Use in edit view (in window) big design as in old dynamic playlist.
> - Show percentage in normal view. The possible place is before the
> left of labels and right of bar for each proportion.
> - Show percentage in editing view in window at the right of bar as in
> old dynamic playlists.
> - Provide functionality when user can change the proportion by writing
> numeric value in textbox. Think the textbox should be the textbox
> described in previous paragraph.
> - Add button "max" at the right of editable percentage textbox to get
> rid of proportions deficient.
>
> Why this is bug?
> and not wish? The reason I set it to Minor bug is that the situation
> was bad yesterday, is bad today and might be bad in the future. It's
> difficult to use current Dynamic playlist. Think, this is good place
> to discussing about Dynamic playlists and solve the problem once and
> for all and won't change it from one to another releases.
